My screen is a user-defined 25 lines Antic 4 (Graphics 12) with 1000 bytes. In my program I defined variables to content memory screen, display list and charsets. Actually Im thinking there is a memory conflict problem, and I read that could be fixed using a linker file that define memory areas for CC65 programming. Althought, its difficult for me, to understand how to create a reasonable linker file. At this point, I removed a portion of my code program that Im not using, and fixed the garbage problem. But, im sure when i continue in adding code, the garbage will appear again. But, I had created again the garbage and send you the state. farmer.zip When I add more code in my program, the garbage grows to the top of screen, line by line.

Thanks for the help. It's more than the books showed me. Im programming in CC65 and sometimes I get a corrupted screen. The Debugger said the DLIST is good and the memory screen map is ok, but I get a screen like: Some garbage is allocated at the bottom screen, but the screen memory shows the correct data. Sometimes when I move or delete some variable, the garbage disappear. I think is a conflict memory, but I cant figure why the debugger dont show me the garbage.

Recently I use Graph2fnt like a tool for create giant sprites images. But I feel there are 2 simple but useful add-ons: - A selected image area can be moved pixel by pixel (with arrows + SHIFT) - A selected image area can flip horizontal and vertical in mirror mode. - In screen char mode, where you point a char, shows like a hint the Internal number code.

Thanks Heaven, I saw and read every time these good resource, but in my humilde opinion there are some mistakes. Maybe, because was wrote oriented to 800 machines. It's a pity don't exist a good XL/XE resource.

Did you try to say me, "1K boundary" means a number pointer address divisible by 1024? Is this rule applied for Display List address too? P.D. Another internal mistery 8-bit resolved Thank you!

I create a text screen Antic 4 and print at screen all fonts that I redefined previosly. I cant explain whats wrong? I send a save state for debug with monitor. In the monitor we can check Display List: m 230 and get the DL adress is 2970, then: m 2970 and get the Display List, 4th and 5th value is the screen address (338C), then: m 338C I see the values that I print in the screen: 00 01 02 03 04 05 06 ..... At this point I can see my new redefine charset at: m 2f4 I see high value 2A, then my charset is at 2A00, then: m 2A00 And i see the correct value data, starting with a blank char (00 00 00 00 00 00 00 00) with internal code 00 that was printing at screen, but the screen show garbage. I read that 2F4 only hands number divisible by 2, my number 2A is divible by 2. What could be wrong? I send the save state if you want to see the example. farmer.zip

Andy, You must only use a DOS emulator in your PC for setting and run the compiler. I think you can use DOSbox. Then set the enviroment like I said at my previous post. I send a C sample program, create a file prueba.c with: This program fills the screen Graphics 0 with characters. Dont fall, the first time always is hard, but then you rewarded with the best C enviroment programming in Atari.

Hi, Im not an expert C, but I think I could help the first steps. 1. Unzip your files in a directory C:\CC65 (you may choice another path). In this tree the Bin folder have the compiler and linkers programs. 2. Create a file called SETCC65.BAT with notepad and save at c:\windows directory (we need at the default path). This file contents: set CC65_LIB=c:\cc65\lib set CC65_INC=c:\cc65\include set PATH=%PATH%;c:\cc65\bin This file set the enviroment of CC65 work and get path access to the compiler and likers programs. 3. Create a file called CC.BAT : del %1.xex cl65 --start-addr 0x1000 -Osir -t atari -o %1.xex %1.c IF ERRORLEVEL==255 GOTO FIN %1.xex :FIN This file compile your .C code and executes directly in the emulator. These steps works in Windows, I think you easily translate to the MacOS enviroment. When you start a work in windows you must start a CMD windows (DOS Window) go at your directory work and execute SETCC65 command only one time. After that you may compile your program with: cc program Off course, you need a notepad or better the Ultraedit-32 software to write your programs in CC65. Its very easy and very fast to write and compile in PC or Mac machines. I suggest you adquire a example program to get the first idea of C Atari programming. Don't forget you need: - CC65 - A good editor like Ultraedit-32 - Atari emulator - A source example of CC65 Atari program - A good knowledge of programming Atari hardware, you may review at www.atariarchives.org - Finally, at the very last, a real machine with SIO2PC adaptor Good luck!

CC65 at www.cc65.org I used recently last months with relative success. Easy to use, and powerfull if you mix with assembler routines.

Only accept ZIP files

Sounds like a "Armalyte" or "Tusker" SID efects ... cool

What happens with artifact colors?

Fine!... but only HiEnd Smooth option cause noise with the music background. I tested with Space Harrier demo. Digitized voice not sounds, only I hear garbage. P.D. I have a Atlon 1200 with ATI 8500 AIW video card. The noise is because this HiEnd mode forced my machine at the limit. ***

Really Cool ! I have tested with Space Harrier Demo and the digitized voices didnt sound

Do you remember great arcade game CRUSH ROLLER?, well Ms.Bulimia is the only game that I remember that seems style in A8.

Yes, but as the best "horrible" creation. I like "progresive dream", I've heard 50 times at least.

Wow! a funny game with a special sense of music and graphics. Sure its unique. Congratulations! I loaded in my 130XE NTSC machine. The first screen appears with full color and without flickering effects. Great! The sounds are solid and very crazy. When appears the level menu I choose the first level, the initial screen game appears and after the redefine char process the machine hangs. Well, I suposse soon will be patched, meanwhile I enjoyed with the emulator. Thanks for your Atarian job.

Really cool game, and the screenshot promises a game with many colors. Keep the work!

It's a pity Atari let some people stole the last Lucasfilm projects ("Ballblaster", "Jaggilines"). These great piece of software is only compared with the best later 90's games. Even now are 10/10 games. That colorful robot screen in motion, I'll never forget. Still im awating the day that incomplete Laberynth Atari project leave to the domain public.

William Moloche created a intro in 1991. That's all. Some people here had seen his intro. Great site atari.fandal.cz (Thanks Fandal! ) have the intro. Please Fandal, how do you got this file? I thinked lost. Ninja Mutant Teenage intro

On NTSC machine and TV, the flickering is practical inexistent on this special modes.

Outstanding work!!! A NTSC machine, isnt it? ... I want one

I can imagine Rob Hubbard trying to programming one of his best music in a simple 8bit wide 4 channels POKEY, really he should take more time to finish. I dont remember where, but I read Hubbard copy the IK music from a japanese song.

ehhh??? off course Atari version have music and sound at the same time. Only press T for Music and sound and press CTRL-T for Sound in game screen

Its a pity Rob Hubbard didnt create a complete music version for Atari. Basically the real music has 3 different parts, and Atari Music IK has only 2 of them. I think that was for save memory for 48K compatible 800 version.
