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 2015E TI-99/4A RXB 2015E 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 or Hard Drive Access or updated CALL routines. The below RXB tutorials on Youtube give a good overview of RXB's power: RXB DEMO 1 video RXB DEMO 2 video RXB DEMO 3 video RXB DEMO 4 video RXB DEMO 5 video RXB DEMO 6 video RXB DEMO 7 video RXB DEMO 8 video RXB DEMO 9 video RXB DEMO A video RXB DEMO B video RXB DEMO C video Full documentation, examples and GPL source code included in the ZIP package.

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).

  2. I looks like I screwed up. A little while back I posted a blog about Harry's 40 column routine he created for the TI-99/4a. I also added a the game Civil War. After rechecking the blog I discovered the two files I posted were the wrong files. ACK! So, here are the right files and a little more. I have the T40XB utility on .DSK and my XBBOOT.DSK which included the T40XB on a menu along with TML & KXBII. And I have a directory with all the games I have posted so far. Here is the correct files. Downloads.zip
  3. 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
  4. 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
  5. 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
  6. Here is another conversion from my Atari BASIC programs to the TI-99. It's a Yahtzee game. I never liked any of the Yahtzee for the Atari 8-bit so I wrote my own. This is mostly a direct port of that game except for the graphics. On the Atari I used DLI to change the font sizes on the fly which can't be done on the TI-99. But, I used Harry Wilhelm's amazing TML program for some other graphics. TML gives the XB programmer access to the bitmap graphics of the TI video chip. You can create Cartesian point graphics, boxes, circles and multi-colored fonts, loading hi-rez screens and much more. It's similar to the KXB package I used to create Uno with but with much, much more power and, in some cases, more stable. On writing the program. Yahtzee is a fairly simple game so wasn't much to create the original game. the only hard part was the logic to print what could be scored with the roll. the -small straight- logic was most complicated. my solution I thought was rather cleaver. programming the graphics in TML was fairly straight forward. Harry has created a wonderful manual for TML and some examples on the disk. One thing to note, since TML has to, more or less, draw each letter on the screen in bitmap graphics, it a little slower then if I have just used 'display at'. still, it's not all that slow. about average XB slowness. I'm attaching the TML package, my XBEAboot .dsk and the game .dsk. the game auto loads TML then the game. look on the XBboot disk is a program called DT. this is a directory program that runs under TML. and standard DIR program (like the D program also on XBEAboot) won't run in TML. enjoy the game. oh, I'm also including a .vbs script that can be modified to auto load MAME/MESS TI-99 .disk games etc.. from Windows. enjoy. yathzee.zip

  8. 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.
  9. 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
  10. 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.
  11. 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!
  12. 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
  13. 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.
  14. created a new XB game for the TI-99. check out my blog for download. Enjoy
  15. 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!
