pixelmischief Posted May 16, 2020 Share Posted May 16, 2020 Where can I get assembler source, for commercial-quality games, that has been released to the public domain. I want to get a look at how the big boys are accomplishing a few things that I am simply at a loss for how to do. Quote Link to comment Share on other sites More sharing options...
Wrathchild Posted May 16, 2020 Share Posted May 16, 2020 You recently had Plastron sources: @MaPa generously includes many of his sources Way back there was also Jellybeans Though more a disassembly, you could also study Mastertronic's Colony Quote Link to comment Share on other sites More sharing options...

Rybags Posted May 17, 2020 Share Posted May 17, 2020 A few Atari games out there, even including Star Raiders. Though I'd not recommend it as a learning example. A more simple 2D game would be better. Plus plenty of scene/homebrew games over time have had the source code released, some even in parallel with the game itself.

Graham Dearsley Posted May 18, 2020 Share Posted May 18, 2020 I would love to have a look at the source code for the Atari Galaxians cartridge or does anyone just know how they managed to put so many colours on the moving Galaxians ?

I believe that game used characters for the main formation, allowing for 5 colours per object. Quote Link to comment Share on other sites More sharing options...

You guys collectively know more about the computers than the original devs did. 1 Quote Link to comment Share on other sites More sharing options...

R0ger Posted May 21, 2020 Share Posted May 21, 2020 Things like this can be easily analyzed in Altirra. Use ctrl+F8 to switch layer mode, that will show you what is PMG, and that is which field. Next ctrl+F8 will show you color registers changes during the frame. And if you break into debugger using F8, you can then use Alt+click on screen, to see what is the current Antic mode, VRAM address and DLIST address for line. That can give you some idea. 1 1 Quote Link to comment Share on other sites More sharing options...
