I agree COMPLETELY with you Large Dopant white. When I get good enough at programming to release something worth while, I will be severly pissed off if someone rips off my source code like these people have. I did not know about people not giving props to the original authors, the only two I have used are MAMEX for Metal Slug 1 and 2, and xSNES9x. I never really check credits, but I would still feel better to know they ARE getting credit.
I have decided to never release my source code except to trusted and proven people after I make it, unless it falls under a specific lisence like GPL. I know there is no way to legally release it, but I don't really care about using the XDK to compile it. Anyway, I am not really interested in porting anything to Xbox, but am more likely to work on GBA and Gp32, and newer handhelds (Helix, N-gage). I still love Xbox, but now I can't really think of anything that needs to be ported...maybe a saturn emulator, but I still have a saturn and I never thought it was that good anyway.
