Hi there :D
First of all sorry for my english.
Im more of a designer profile, i dont know much about linux and Pi, but i love the idea behind this project. I can play a few games (most of them are broken roms, i guess that this is a problemof the rom not the PiPlay) but when i play a game i can't get the joystick work... the only way is to remap all the buttons for _that_ game when i config the general inputs they dont work :(

Also the "coin" button doesnt work i guess i need a little more of try and error on that becouse i cant get to remap it

Also, im a designer, i would love to help with this project. This is my portfolio http://abadfederi.co/
