Mathy Posted March 21, 2013 Share Posted March 21, 2013 Hello CyranoJ That's right. The 6502 is the CPU, the 68000 in this case is just the IO chip. Sincerely Mathy 3 Quote Link to comment Share on other sites More sharing options...

Kr0tki Posted March 21, 2013 Share Posted March 21, 2013 M.W. Colburn did some other Atari 8-bit stuff such as the Atari 1200XL BIOS, so he was definitly an Atari 8-bit guy. More specifically, he is the original author of Self-Test. The only name I can find in Tennis is this: (...) * Greg Riker * (...) Does this name sound familiar? His name also appears in the source code of the 1200XL boot-up screen (not used in production), as posted by Curt himself a few years ago.

Tempest Posted March 21, 2013 Share Posted March 21, 2013 I got a chance to play Defender on the real hardware. It works but bombs don't work. Allan What are you using to play it? I wonder if we can get an .xex for this. Quote Link to comment Share on other sites More sharing options...
+Allan Posted March 21, 2013 Share Posted March 21, 2013 What are you using to play it? I wonder if we can get an .xex for this. It is an .XEX. Just put it on a disk and use the L, LOAD function to run it. I used DOS 2.5. I had to disable the ramdisk program first but once I did that it ran fine. It ran fine in the ATARI800MacX emulator as well. I'm sure it will run in the newer PC Atari emulators as well. I could not get the Fooftball game to run though.

peteym5 Posted March 26, 2013 Share Posted March 26, 2013 Imagine what kind of hacks we can do with these games. They would have to be ported to .asm text files because the return / tab characters are different. I could bring it up in notepad and know its 6502 assembly. There's a few games I wouldn't mind seeing modified to make them closer to their arcade counterpart. Quote Link to comment Share on other sites More sharing options...
108 Stars Posted April 6, 2013 Share Posted April 6, 2013 (edited) 68000 isn't the same as 6502. And that's exactly why you and Kevin should take this chance and get your toes wet with the Lynx, which is a 6502 system and would be just perfect for ports of those games.

Fres Posted April 13, 2013 Share Posted April 13, 2013 The released version. There were two released versions. One has a 1982 © and the other a 1983, if I remember correctly. I have both carts. They both have the same label (brown with 1982 ©). I believe there were also some gray label releases of the 1983 version. Quote Link to comment Share on other sites More sharing options...
Tempest Posted April 13, 2013 Share Posted April 13, 2013 Correct. There's the original 800 release and then there's the 5200 version that they also released on the 800. I assume this source code is for the original 800 version. I was wondering if the source code was different. Quote Link to comment Share on other sites More sharing options...
zigster Posted April 15, 2013 Share Posted April 15, 2013 The 800 and 5200 versions were completely different code bases. Quote Link to comment Share on other sites More sharing options...

Tempest Posted April 15, 2013 Share Posted April 15, 2013 The 800 and 5200 versions were completely different code bases. I know that. I guess I'm not making myself clear. Is this source code different from the earlier 800 specific version that was released first? Quote Link to comment Share on other sites More sharing options...
zigster Posted April 15, 2013 Share Posted April 15, 2013 This is the source code for the earlier 400/800-only game cart. I don't know if it's actually the finished, released version of the codebase or not. It was written before the 5200 even existed as a console. Is that the right answer to the right question? lol Quote Link to comment Share on other sites More sharing options...
Tempest Posted April 15, 2013 Share Posted April 15, 2013 I don't know if it's actually the finished, released version of the codebase or not. That's what I wanted to know. There are two earlier versions of the 800 only release out there (check AM) and I was wondering if this was different from those. Obviously we don't know the answer to that yet.
