I want to do a GameBoy Advance emulator for WP7 but I'm not sure where to start. Anyone can point me in the right direction? I know there is one for GB, maybe starting there would be a good idea. Any libraries or resources?
You can download the source for VisualBoyAdvance here: http://sourceforge.net/projects/vba/files/VisualBoyAdvance/1.7.2/
It's one of the most well known and reliable GBA emulators and it's written in C++, so it shouldn't be too hard to port over.
