Open or Example Assembler Source Code

[pixelmischief]

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.

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

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.

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.

Also, don't forget to just ask stuff here Lot of knowledge among the AA users.

Lol, that's putting it mildly. You guys collectively know more about the computers than the original devs did.

Source code for the 5200 version of Galaxian is here.

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.
