Thanks for the tip, and yes, we have abandoned our original idea as it was making my friend bald from frustration. But one point you made is exactly what we are currently trying to do.... Bundle an emulator and a rom together as a stand alone application that can be intalled like any other .apk, so when selected it can run without any other outside programs. Emulators are small in size so it wont take up too much space when bundled. I know this can be done on windows and linux emulators but i am having trouble wrapping my head around this, both the bundling of the emulator and rom, and converting it to an apk.
Oh and your project lookd very good, i like the idea and the interface looks nice and smooth
