  1. Here is the Star Trek game I posted in the very 1st post of this project blog. There it was a completion of several of the games I had posted as a kid to the TI99IUG. But it's such a neat little game I decided to make it it's own post. It's a real snap shot of the BASIC/XB program that was done back in the 80s. I made some minor updates but it's still essentially the same. It's a TI-BASIC program that was converted to TIXB. Some cleaver graphics and sound. Instructions included in the program. It self starts in XB. TREKXB.dsk
  2. What we have here is my 1st attempt at using Harry's XB compiler. All I can say is, WOW! that's fast. The game is an Othello game I typed in from some? book and summited to the TI99IUG waaaay back when we used to type in such things from dead tree sources. It was originally in good ole' TI BASIC. The game was painfully slow, really slow, I mean, get a cup of coffee, drink it, piss it out and maybe the computer would have made a play slow. I later, much later like, 2018 later, rewrote it and tightened it up in XB. Now you could just go get a cup of coffee and a sip before the computer made a play. Still slow. That made it a perfect candidate for compiling. What I expected was a moodiest speed increase, make it playable increase. Instead what I got was a, blink and you missed the computer play, fast. Wow! This compiler makes so really fast code! If you follow Harry's documentation and play within the limits the compile is stupid easy. My 1st compile returned no errors and played the 1st time. The game is a simple version of Othello. Graphics are fair to good and the play, as stated, is fast. There are 3 levels of play and I can tell you Level 3 is very hard to beat. You can specify Computer or Human start 1st. Nothing more except did I mention it was FAST ! The download file contains the self boot game on .DSK and the official rules for Othello. Enjoy, HLO othello256c.zip

Playground TI-99/4A Playground is a package making it possible to create assembly language programs that run from TI BASIC on an unexpanded console using only a cassette player to load the program(!) Although primarily intended for use in TI BASIC, programs written for playground can be run from XB, saved in E/A 5 format, loaded into a supercart, and even made into an actual cartridge. The manual describes in detail the differences in style necessary when programming for an environment that runs in only 256 bytes of memory. There is a library of subroutines for printing text, printing a number, shifting blocks in VDP, generating random numbers, using the line editor from BASIC, HCHAR, VCHAR,GPLLNK, a bit reversal routine, and a fast scroll routine. Source code is included for three different programs that should help you get started. Check here for the development thread on Atariage. Check this related thread for some clever work based on Playground. (Author: @senior_falcon) Extended BASIC - Software Extended Basic Game Developers Package "ISABELLA" TI-99/4A This package has been extensively updated to be faster, more versatile, and much simpler to use. It consists of two applications that make it possible to produce arcade quality games with XB. Although they are designed to complement each other, each is a stand alone utility. This is meant to be used with the Classic99 emulator, but the resulting programs are fully compatible with a real TI99 with nothing more than XB, 32K and a disk drive. Note that the included XBGDP package has an option to use the older TI BASIC only runtime routines if desired. It replaces for the older "Harry Wilhelm's BASIC COMPILER" and as a bonus, it's much easier and faster to use. (Author: @senior_falcon) 1) XB256 XB256 lets you toggle between two independent screens as desired. Screen2 lets you define all 256 characters and have up to 28 double sized sprites using the character definitions available to Screen1. Scrolling routines let you scroll characters left, right, up, or down or scroll using single pixels. There is a text crawl that gives an effect similar to the STAR WARS title screen. You can highlight text, set the sprite early clock, print in any direction on the screen using 32 columns, read/write to VDP ram, write compressed strings or sound tables to VDP ram, play a sound list, and catalog a disk. A utility lets you save selected areas of VDP memory as compressed strings that cn be merged with your program. With this, character definitions, sound tables, screen images, etc. can be saved in a more compact form that can be loaded virtually instantaneously, even in XB There are two utilities that convert the CALL SOUNDs in an XB program into a sound table containing music and sound effects. Sound tables can be loaded directly into VDP memory and played automatically while your XB program does other things. Also, a second player can play a different sound list simultaneously with the first, so you can have backgroundmusic playing and add sound effects on top of the background music. 2) XB COMPILER COMPILER lets you compile an XB program into an equivalent assembly language program that will run about 30 times faster. All the XB256 subprograms are supported by the compiler and in general, all the major features of XB are supported, including XB style IF/THEN/ELSE and named subprograms. About the only XB features that are not supported are DEF and the trig functions. T80XB TI-99/4A T80XB is a collection of assembly language subroutines that give the Extended BASIC programmer easy access to the 80 column screen mode offered by the F18A and other 80 column upgrades. Lets you select from two independent screens. G32 is the default screen when a program starts running.. This is the 32 column graphics mode screen normally used by Extended BASIC. It is accessed using the usual XB graphics statements. T80 is the 80 column text screen which offers 24 rows of 80 columns.. You can toggle between the two screens as desired, preserving the graphics on each screen. When using the T80 screen there are assembly equivalents that replace PRINT, CLEAR, COLOR, INPUT, CHAR, HCHAR, VCHAR plus routines that will scroll the screen and invert text on the screen. (Author: @senior_falcon) RXB 2020E TI-99/4A Rich Extended Basic (RXB) 2020E is an updated version of TI Extended Basic. Most bugs in XB have been fixed in RXB and GKXB is in the main core of RXB. RXB has features no other XB has such as batch processing, SAMS support, hard drive access or updated CALL routines.

Kaal) GNU C Compiler (GCC) win + linux + osx GCC for the TMS9900 allows you to cross-compile C programs on your PC (Linux, OSX or Windows) for the TI. Insomnia's release contains a set of patches against GCC 4.4. Just check out the code from the GCC project, apply the patches and build according to the build instructions for your platform and you're on your way to write programs and games for the TI in a high level language that rival the speed of assembly. And if you need just that little bit extra in terms of speed, you can always inline TMS9900 assembly for the critical sections of your code and compile everything with the same toolchain. For access to the VDP, the SN76489, etc... you can use Tursi's ti99 library, which you can find in the GCC thread. Hop over to the INSOMNIA LABS blog for background information on this port. Check the "Setting up the GCC compiler for the TI-99/4A" video by @Tursi for detailed steps on how to build and install GCC on your Windows PC. You can now download the cygwin binary port of the older TI GCC 1.10 for Windows here. (Thanks @lucien2).

  4. Here is the Uno+ TI-99/4a Extended BASIC version of the Atari Microsoft BASIC Uno+ that was an updated Uno that had been ported from the original TI-99/4a in that had been created using the KXBII Extended BASIC programing package. Got that. Anyway, here is the game and a fun one it is. It has color, it has sound, it has speech, it plays a fairly fast game and includes several of the variations of Uno. You can also save your games parameters to disk so that you wont have to type them in each time. To Play: the bottom 4 lines are the letters for your cards marked by color; red, yellow, green and blue. last line is Spl which is the change color cards with C (change color) or F(play draw 4 change color). the types of cards beside the colors are 0-9 D=draw 2, S=skip and R=reverse. under Spl are C=change color and F=draw 4. when the human plays you choose SORT, PLAY and TAKE. SORT just sorts your cards. TAKE will take a card from the pile. PLAY will play 1 of your cards. in Play you type the card you want to play by following the prompts. the game plays a standard game of Uno except; Uno call is automatic and has 1 in 12 chance of 'forgetting to call a Uno penalty which is also automatic. The original version was the simple standard rules of the game. But the real fun of Uno is the various versions of the game that one can play. So I went back to program and added several of the additional game versions to spice up the game, and a little sound and speech too. There are six new versions of game play: 2S as pick 2? - this version has the 2 card as aTAKE 2 for ALL players. Play a 2 and all the other players will have to take 2 cards. 7S swap cards? - Play a 7 and you can swap your cards with any other player. Take till play? - when you have to take a card you must KEEP taking cards until you get to one that is playable. DRAW4 only? - you can't play a DRAW4 until it's the only card playable. Good Take must play? - When you TAKE a card, if that card is playable, you must play it. NOTE: If TAKE card is playable you get a beep then the game rolls you back to the SORT, PLAY, TAKE screen. The other 3 computer players play a very good game. I programed in that sometimes they will mess up, but not often. I found I win about 1 in 4 or 5 games, which is a good average. The game disk auto-boots a loader program which in turn boots the Uno+ game. Anyway, enjoy the game. unoplus.zip
  5. Update: moved packages to emulation section from software. I have put a together MAME/MESS emulation package that emulates the MyArc Extended BASIC II & TI P-Card for the Ti99. MyarcXBII: MyArc was a company that made peripherals for the TI-99 line. There most famous peripheral (if you want to call it that) was the Geneve. The Geneve was a complete TMS 9995 computer that fit in the TI-99 PEB as a card. Another peripheral that was lesser known, but just as revolutionary, was the MyArc Extended BASIC II. The MyXBII consisted of the 128k or 512k Memory card, a set of disk and a cartridge. When running the MYXBII had 3 times the memory of TIXB, was up to twice as fast as TIXB and was able to access all the graphic capability of the TI graphics card including the hi-rez. If a MyArc HD disk card was added the software could even boot from the MyArc hard drive. It turned the TI99 into a real power house. Unfortunately because of it's expense and the fact that you needed a PEB to run it, the MyArcXBII never really caught on. Now, though, with emulation it cost nothing so through the power of MAME/MESS the power is being released. Start the MyArcXBII at the TI99 main menu by choosing 3-128k BASIC and this will boot the MyArcXBII from the hard drive. P-Card: The P-Card was a card for the PEB that was, more or less, a complete operating system apart from the TI99. It's a virtual machine processor on a card that ran P-Code. It was written totally in software and was based on Pascal and was able to run on other computers that also conformed to the P-Code specifications. It is nothing like a standard TI-99 and when booted takes over the TI-99 and even has a specially formatted disk it uses. There is a complete suite of software and if you can figure it out, kinda nice. To run the P-Card in MAME/MESS click under OPTIONS-DIP SWITCHES then turn on the P-CARD. Hard reboot the machine and the TI-99 will start in the P-Card mode (after a few seconds of beeping and blank pages). To go back to MyArcXBII just turn the P-CARd switch OFF then hard reset the machine. The MAME/MESS package works with any versions of MAME/MESS past version 222. Just merge your version of MAME/MESS into the MESSxxx directory and point the already created batch file in the root to that directory. Package includes manuals, software, batch files and everything you need except MAME/MESS itself. Enjoy. Download from my https://ti99resources.wordpress.com/emulation/ At the bottom of the page is MAME packages, click on MyArc Extended BASIC II to show download files. I have both a package with and without the P-Card. (a truly nice tripped out Ti-99 from mainbyte.com)

  7. i saw this video on youtube https://www.youtube.com/watch?v=0yKwJJw6Abs and i thought, i can totally do that on the TI.. so.. 10 D$="FF" :: FOR D=65 TO 65+8 :: D$="00"&D$ :: CALL CHAR(D,D$) :: NEXT D :: FOR B=1 TO 10 :: PRINT "F";"E";"D";"C";"B";"A";"A";"B";"C";"D";"E";"F";"G"; :: B=1 :: NEXT B i had to print each character individually to get the required screen movement.. Here's xbasic, and compiled.. WAVE is normal extended basic, -X is compiled but loads in extended basic, and -E is EA5 load. looks pretty slick compiled some small screen glitches likely because I'm running classic99 in Wine on a linux pc..

  8. After a long time of procrastination I have finally got around to updating the Mille Borne for the TI-99 in Extended BASIC. I have added some sound effects, some voice CALL SAY("UHOH"), sped up parts of the program and cleaned up some minor bugs that had been long standing. This is 'probably' the last version but I have learned never to say never. The game is XB autoboot and is in .DSK v9t9 format. Enjoy. MILLEBORNE-V340.dsk
  9. Hi Guys, yesterday I have run into a nasty Syntax Error in Extended Basic, which also occurs in RXB. I don't understand it and wonder if the line really contains a Syntax Error or this is a Interpreter Bug. Version 1: 1 IF A=1 THEN 2 ELSE FOR I=1 TO 2 :: PRINT I :: NEXT I 2 END Version 2: 1 IF A=1 THEN 2 :: FOR I=1 TO 2 :: PRINT I :: NEXT I 2 END Both versions complain about a Syntax Error in Line 1. I would like to analyze it with the help of you and maybe RXB can be even fixed.
  10. Another Extended BASIC game for the Ti-99/4 line; Star Merchant. Back in the 80's there were several variations of this game where you traded merchandise between star systems. The game dates back to at least August 1981 when Creative Computing published the game but probably goes back even further to the mainframe era. I seem to remember playing something like this on the TI mini-frame in school. Simple game, you buy merchandise in one star port the 'Warp' to another star port and try sell it at a profit. The version I am posting is a modification of a Atari 8-bit version that Creative Computing sold through a 3rd party. I again use Harry Wilhelm wonderful 40 column routine as I used with the Civil War program. Only difference is I'm using the inverse utility in T40 to livin' up the text. Translating from the Atari 8-bit was fairly straight forward for this program (not like the Mille Borne which took and almost total rewrite). The two things that were the big difference was, of course, string usage and the fact that with the Atari you can have a variable line number in a ON GOTO and ON GOSUB statement (can't with the TI ExBASIC). Included is a copy of the manual for T40, the auto LOAD .dsk of the game and a copy of the original text from Creative Computing Aug, 1981 where the game was printed. Enjoy, HLO star-mech.zip
  11. I have been going through my Atari 8-bit games and looking to translate them into TI-99 games, mostly BASIC. The games I wrote in Atari MSBASIC are fairly straight forward translations. Atari BASIC has the issue of strings being completely different but can be got around. One thing that both Atari BASICs have in common is the Atari uses 40 column text. This can be a tedious issue to fix when translating to TI99 32 column text. You have to go through each line check, recheck, reformat recheck again etc... It would be nice if the TI99 had a 40 column text mode... oh wait, it does it's just not easily accessible in XB. But some nice people, much smarter then I in all thing TI99, have addressed this deficiency. Enter the 'Senior Falcon' (Harry Wilhelm) with a wonderful little utility called T40XB which makes the 40 column mode usable from XB. For more on it read this thread: http://atariage.com/forums/topic/289953-40-column-routine-or-early-version-of-xb24-for-xb/ Simply you use CALL LINK routines to call the T40 and use the 40 column routines in it's own screen. Here is the file: T40XB1.zip the ZIP file has a very nice booklet with it. Now to the game. To test this 40 column routine I chose the simple game 'Civil War'. It's from David Ahl 'BASIC computer games book'. Here's a copy of the book online: https://www.atariarchives.org/basicgames/ How I got this game from the Atari to the TI99 was thus: 1.) load the game in Atari Altirra emulator. 2.) print the game to text. 3.) do global REM of lines that the TI99 won't understand (such as POP) 4.) global replace PRINT with CALL PR(.. 5.) create CALL routine: CALL PR(A$) CALL LINK ("PRINT",25,1,A$) SUBCALL 6.) Now go through the program and change other things such as INPUT and replace multiple PRINTs with SCROLL 7.) start classic99 and paste in the code and save, test, save, test ..... All in all this conversion didn't take that long since string use was minimal and I didn't have to go line by line reformatting. The T40XB does eat into the stack area in the VDP so you will have about 2k less memory for created CALLS and string arrays. It doesn't use any main memory though. It does, currently, have an issue with classic99 sometimes locking up the emulator but Tursi is looking into that. Here is the game disk: T40XB1.zip from the menu press 2. It starts the T40XB package which calls the civil war game. now lets look at some of the commands of T40XB: First off the 40 column mode is one color; that is one fore and one background color. Also you have no sprites. This is a limitation of the TI99. You must load in the T40XB using the loader program, DSKn.TX40XB. Afterwards CALL LINK("T40") to turns it on. You must have this as the 1st line before you do anything T40 related in your program. All the T40XB text lives in it's own memory area so when the program ends or you jump back to the 32 column mode using CALL LINK("G32") your T40 text will disappear. CALL LINK("COLOR”,foreground-color,background-color) this changes the fore and background colors. Standard TI99 won't work. CALL LINK("CHAR”,character-code,pattern-identifier[,...]) this is CALL CHAR for T40. You get a separate character set for T40. Harry has already supplied a nice character set with true lower case. CALL LINK("INVERT”,row,column,length[,...]) this gets you inverse text much like the Atari has (nice touch). a lot of the other commands also have an inverse mode. CALL LINK(“SCROLL”[,repeats]) this will scroll the page up 1 to [repeats] lines. CALL LINK(“CLS”) this does a CALL CLEAR CALL LINK(“HCHAR”,row,col,character-code[repeats,.....]) & "VCHAR" same as TI CALL HCHAR & VCHAR. CALL LINK(“PRINT”,row,col,string or number[,length,.....]) this is the meat of the program. It is a combination DISPLAY AT & PRINT. If you specify the row & column it will display at that row & column. Put 25 in the row and it will print at the bottom of the page and scroll everything up just like print. Note: you must have a properly formatted string to display. Errors might crash the TI99. CALL LINK(“INPUT”,row,col,string-or-numeric-variable[,length,prompt-string]) this is INPUT AT or just INPUT like the TI99. Refer to the manual for lots of features. One nice thing is that if you crash or exit the program the T40 routine exits gracefully. Good programming. Not many commands but it gets the job done without not much overhead. Very nice. Well, that's it for now. HLO XBGames1.dsk
  12. Converted my Atari 800 game Uno card to TI-99. I used the KXBII extensions to create multi-color text. (see earlier blog post for Uno for Atari 800 and KXBII extensions for TI-99/4a). Plays at TI-99 XB speeds, which is to say, fast enough. The multi-color text is part of the KXBII extension package. Works rather well & fast enough and bug free. Only weird glitch is 1/2 character random flicker in one letter (you'll see it) when text being printed. I created a CALL PR(X,Y,TEXT$,fore-color, back-color) SUB-routine for printing to simplify conversion from Atari 800 MSBASIC. attached is a booklet and the .DSK bootable disk game. Enjoy. uno.zip
  13. Mille Borne is a French card game of auto racing currently being sold by Parker Bros. The actual card game can be played with 2-6 players but the computer game is 2 player only; you vs. computer. The object of the game is accumulate enough mile cards to make it to the finish line. But there are hazards along the way that will keep you from that goal. If you haven't ever played the game refer to the manuals I have included with the game .zip file. in this computer version there are a few differences. a.) to start the game you can choose a long game (standard 1000 miles/5000 total) or short game (700 miles/3000 total). b.) when playing a safety or Coupe Fourre you don't get an extra turn. (it was too much trouble to implement). I think everything else is the same. some history on the program. This game is a translation of a game I have had on the Atari 8-bit forever. I have no idea where it came from on the Atari. I would love to credit the programmer but have no idea who he or she is. On programming the game. As I said, this is a translation from Atari 8-bit BASIC. At first I thought that it would be a direct translation but the differences in how the strings work on the Atari BASIC to convert to TI-XB turned out to be too time consuming. So, basically, I just rewrote the TI-XB with guidance from the original program. Some of the code looks a little, out of place. this is usually the code I pulled directly from the Atari BASIC. This probably makes the code a little slower than if I had programmed it in TI-XB from scratch but I didn't want to spend an additional week to just fine tune for a few seconds of speed. Anyway, enjoy the game. UPDATE: forgot to mention, I have a small simple routine that redefines the character set to true lower case. only takes about 3 seconds to load in XB. should even work in console BASIC. just cut a paste into your program. millborn.zip
  14. I don't know how much cross-over there is in this TI-99/4a sub-group with the Atari 8-bit home computer sub-forum, but I presume since this forum is hosted in the AtariAge forums that there must be at least a few people who collect for both computers. Right now, I have a six books for books for the TI-99/4a computer. They're the one's in my first TI video: https://www.youtube.com/watch?v=eoBjUDMar84 I'm looking to expand the TI books that I have currently in trade for spare Atari books that I have in my personal collection. Is anyone interested in doing trading books with me? If so, then I'd like to use this thread to post the books I have, and others can post the books that they have for trade. If a few people like this idea, then over the next few days I'll make a list of TI books that I want and a list, maybe with pictures, of the Atari books that I have for trade. So... is anyone interested in trading their spare or unwanted TI books with me? Adam P.S. Oh, and if you have no interest in Atari books, then you can always give your spare TI books to me...
  15. created a new XB game for the TI-99. check out my blog for download. Enjoy
  16. So I've been thinking about extended basic lately and that it is the go-to language on the TI-99/4A. We've seen multiple extensions to Extended Basic, like for example Gram Kracker Utility 1 which probably generated one of the first enhanced Extended Basic versions. We also have Rich Extended Basic and now Extended Basic G.E.M. Also don't forget the work on SDD99 that is enhancing Basic in multiple ways. Just for fun, and who knows what happens next in the future, I'd like to collect ideas on how an Ultimate Extended Basic should look like. What the benefits are, etc. I'll kick it off with following proposals: Compatible with existing Extended Basic Fully runs from cartridge space so that we get as much program space use out of 32KB memory expansion as possible Built-in support for SAMS Full-screen editor or advanced line editor as seen in MSX Basic Built-in assembler integrated in Extended Basic, so that you can mix assembly source code right with your extended basic program code. Something along the lines of: http://www.peter-cockerell.net/aalp/html/ch-4.html Full 80 columns support, both for basic program code and line editor.
  17. Just thought I'd take a stroll down memory lane My list off the top of my head in no particular order...

Yahtzee like game) - Close Encounters of the Simon Kind - Zap-A-Ball Xbasic - Meltdown - Bird Brain - Cavern Quest - Window Washer - Survival - Bladerunner - Mean Streets - Blackbeard's Treasure - Meteor Rescue - Bee Line - Tower
  18. Hi guys, this is my first compiled game. It's a simple tribute to the great movie Tron. To use it copy the unziped file in your DSK1 folder (if you are using Classic99). Choose the Extended Basic and write RUN "DSK1.TRON" I hope you have fun! Luca TRON.zip
  19. I know it's pretty early in the morning and my brain hasn't finished spinning up but I don't see whatis wrong. It should be right here and in plain site but I can't see it. The issue I'm having is pretty straight forward. Here's my code 5940 IF YP<>129 THEN 6010 5950 IF LO0T(1,9)<>96 THEN 5970 5960 ZED1=1 :: CALL POSITION(#18,YZ1,XZ1):: CALL POSITION(#1,YP,XP):: DET2=LO0T(2,14)::DET1=LO0T(2,9)::IF XP>=XZ1 THEN ZED1=0:: GOTO 5980 5970 ZED1=0 5980 IF LO0T(1,10)<>96 THEN 6000 5990 ZED2=1 :: CALL POSITION(#19,YZ2,XZ2):: CALL POSITION(#1,YP,XP):: DET2=LO0T(2,14)::DET2=LO0T(2,10)::IF XP>=XZ2 THEN ZED2=0:: GOTO 6670 6000 ZED2=0 :: GOTO 6670 When I run TRACE, everything matches up with what I am observing in game except when it doesn't at the end. Here is my trace: <5940><5950><5970><5980><5990><6000> Everything checks out fine except this: <5990><6000>. How is it possible that the program is advancing to line 6000 from line 5990 when the last statement in 5990 is a GOTO statement to a bunch of other functions? OK, I see an unrelated issue. I'm not sure how DET2 gets assigned 2 different times in one line. That is very strange. I wonder if classic99 or my PC is scrambling things up on me.
  20. Howdy TIers. I hate to start a new thread, but I couldn't find a good place for it. So, I am working on a proof of concept for launching programs from a program: 100 CALL CLEAR 110 INPUT "FILENAME:":FL$ :: IF FL$="" THEN 110 120 RUN "DSK1."&FL$ But this gives * SYNTAX ERROR IN 120. However, if I change 120 to 120 PRINT "DSK1."&FL$ I get the expected string printed on the screen (i.e., if I type in LOAD for the input, I get DSK1.LOAD printed on the screen). Why does RUN not like this syntax? Is this possible through XB, or am I just wasting my time? Thanks for reading!
  21. OK, I know it's just somewhere and probably just under my nose but, I can't seem to find a listing of the I/O errors in extended basic. I looked in the XB manual, the disk manual and couple other manuals. I'm getting a I/O error 25 in a little database program I am writing and figure out why. Which book has a list of I/O errors? (got the CYC so got most of the manuals). thanks, HLO
  22. Created a little package for MAME/MESS that enables MyArcXBII and P-Card in one pre-made package. Just add latest MAME/MESS and go. It's on my project page that accesses my https://ti99resources.wordpress.com/:
  23. I want to show all of you a project that I have been working on and off for a few years now that I feel is ready to be shared, but first, some context: For years I had always wondered how the TI BASIC and XB games would have worked differently if these had been compiled or simply implemented on a faster system. Around 2008 I found a game development package called DarkBASIC Professional that featured a BASIC IDE to create 2d and 3d EXE (compiled, as in fast) games on Windows systems. The BASIC syntax reminded in many ways to console and Extended BASIC but the lack of decent documentation at that time did not give me the confidence to write anything more than a few lines of simple code. Years later, around 2013 I came back to the developer company's web site and found a larger user base, more code samples and even two large tomes of books that thoroughly documented the language. I went ahead and purchased the books and as I learned the 2D graphic features, I started to get an idea of the project I wanted to accomplish. And that's how TI99E originated. TI99E consists of a set of functions developed using the DBPro IDE to simulate the high-resolution graphics, color, string and numeric, input and output functions of the Texas Instruments TI-99/4A computer. DBPro is a free, open-source BASIC programming language suitable for creating Windows applications and games. TI99E programs are developed using the editor and compiler included with the DBPro software. This development environment was created primarily to simulate, as faithfully as possible, writing graphic programs that look and feel like those originally written for the TI-99/4A in TI BASIC or Extended BASIC but without the speed or technical limitations. It also includes additional features that were not available in the original TI BASIC but that enhance the experience of coding TI graphical programs. TI99E is not an emulator; it also does not simulate TI-99 sound directly (it does through .wav files), or many other input-output functions, or file processing. Programs created in TI99E become EXE files for Windows; the BASIC source code is not compatible with the original console, and it is not intended to create programs that run on the original console. TI99E simulates and enhances the following features of the Texas Instruments TI-99/4A computer: - 256 x 192 display size for high resolution graphics - 24 rows x 32 columns screen size for regular ASCII character graphics - Exact replica of the entire ASCII character set from the TI-99/4A - Customizable ASCII characters - 16 colors available for graphics, with multiple color sets - Sprite graphics with auto-motion capabilities - Implementation of sprite collision, magnification, motion, location, position, and distance - Implementation of the TI BASIC graphic subprograms (CHAR,HCHAR,VCHAR,SPRITE,COINC,PATTERN,POSITION,LOCATE,MOTION,etc) - No missing sprite collisions - Modified implementation of Input and Output instructions such as PRINT, INPUT, DISPLAY AT, ACCEPT AT, CALL KEY and CALL JOYST - Math functions using radians instead of degrees: SIN, COS, TAN - String functions such as SEG$, RPT$ - Numeric functions such as SGN, MIN, MAX - Plus, many new features that were not available in the original system: o Up to 1,000 moving sprites at once - yes, and at a fluid 60FPS o Over 1,000 customizable characters and 120+ color sets o Ability to change color to individual characters instead of sets o Ability to create multi-color sprites o Ability to create multi-color characters o Ability to create animated sprites o Individual sprite magnification o Ability to hide sprites and keep them active o No 4-sprite max in horizontal line limitation o Fast, compiled programs o Full-featured Sprite Editor – Supports single and multicolor sprites, load, save, reverse, rotate, mirror, copy, paste and magnify using keyboard or joystick inputs. o Conversion programs to simplify converting original BASIC or XB code into TI99E I call it the TI BASIC that I always wanted. Below you will find the link to the TI99E system, including a Quick installation guide PDF, technical documentation PDF and all the necessary software: - The DBPro IDE - Direct X 9.0C runtime files – required for the EXE programs to run on newer versions of Windows - The TI99E BASIC project files - Sprite Editor – created with TI99E – includes EXE and source code - Conversion Programs – with instructions - Many Showcase programs ready to run and with their source code I recommend using the built-in help files in the TI99E editor instead of the technical documentation PDF. The help files are more complete, updated and organized, plus it is part of the IDE, which is a big plus. The help system includes sample code to test every documented function which, in addition to the showcase programs, is extremely useful to quickly learn the ins and outs of TI99E. The help system is accessible with F1. Just follow the Readme instructions for more details. I really hope you enjoy using this system I created with a lot of care, as a tribute to my beloved TI-99 4/A. https://drive.google.com/drive/folders/1XKvWir9pgkUMoSZJWuHTE6_qKzWi7y7R?usp=sharing
  24. Hey all, I'm trying to make a really long program, so instead of actually wasting all my space with one program I have several programs daisy chained together in extended basic. So far I've had no problems, but things would be a lot less tricky if I was able to send variables between the programs. From what I understand, whenever you start a new program, the variables are all wiped to zero, but you can save values in specific locations on the expanded memory (like 8199 or something like that). I also believe that you are supposed to use (in some combination) init, load, link and/or peek in order to do so, but I cannot figure out how. Anyone know how to do this? Thanks!
  25. Couple of updates here: 1.) Having never had the original manual for KXBII (Kull XBII) I had to make up the manual as I tested it out. One problem that has been plaguing me is that occasionally the disk that I had KXBII (or a program wrote in KXBII) would randomly corrupt. Well after much more testing I found that you need to do a CALL INIT before you save a file after using KXBII. It's notes in the new v3 manual attached. See my https://ti99resources.wordpress.com/ for the complete KXBII package. 2.) the KXBII version of Uno that I wrote on my emulator looked absolutely horrible on a real TI99 with a real monitor. I re-wrote the program to change the colors to look much more palatable. Also fixed and added a few things to both the KXBII version and the standard version. KXBII Manual v3.pdf UNO.dsk
