I ported a CHIP-8 emulator to the iPhone and I just need to work on resolution issues and control issues. The problem is that the chip-8 had 16 keys and I would need to try and make a soft-keyboard :\ I am going to have to modify SDL and see if I can get it to flip the screen so the resolution will be 480x320 and not the other way around, though a game like this might be easy to port to Cocoa. Not to mention I ported it from Dreamchip, which is GPL, but the author said he doesn't want anyone to create alternative emulators, which makes no sense to me Please Register or Log in to view images. The good part is that it had games like pong, tetris, space invaders, etc. and all the roms were 1 kb each! So, before I delve into things, is it worth it?
