MAME On The iPhone
You all knew that it was bound to happen. A developer using the alias Kaisersoze has successfully ported an initial build of the arcade emulator MAME to run on the iPhone.

As is still the case with all homebrew stuff for the iPhone (Apple, will you wake up already!) you’ll have to do some hacking to get it up and running. You’ll also need to know your way around a compiler since you can only pick up the source code and compile it yourself for now.
