I'm starting to develop a MUGEN emulator for Android.
Basically is a classic arcade game that you can play with any characters you want. (marvel, dc, capcom, anime, cartoons....etc)
The first issue that's not Open Source, Elecbyte has not release your codes, but theres is a clone project to help us to not beginning from the scratch. (http://code.google.com/p/xnamugen/)
Anyone join me on this?!
