I am a game developer who has always loved the GameCube system. I've been developing games since 2017 and have been self-teaching and learning various coding languages. I know it's officially unsupported now but is there any way I can make games for the platform still? Google has not been of much help to me so far. Do I need a development SDK or a specific game engine for this task?
I'd also like any and all help and resources related to GameCube optical media security bypassing you can find. I am okay with building my game engine from scratch but my biggest problem is that I have no idea how I'm going to get past the disc verification system. I know that Datel has done it with Action Replay and SD Loader but they haven't made it publicly available what process they used. I know it's possible but the furthest I've gotten research-wise is this article I found that shows how Nintendo scrambled the data.
For clarification, I want to make signed games that can be played on an unmodified system. I also want to released boxed games so it is more like a real game release rather than some hobbyist project.
