Trying to get homebrew running on your PSP? Want to add a screen light to your Game Boy? Trying to figure out how to work your GP2X? By popular demand, discuss it in here! (This forum is for pre-built handhelds, NOT custom made portables!)
It's going to take some time and effort to make this project useful, but I've started a forum and a wiki for discussing Gameboy software development. (For the classic-color range)
The mission of the wiki is to collect existing tutorials and documents on it, and hopefully to produce new material as well.
