We've finally built our MAME machine / arcade cabinet. We've basically been done since the end of the summer (we worked on it all summer long) but never made the final finishing touches until recently as we cleaned up our house for our Halloween party. Anyway, here it is:
In addition to running MAME (basically every game that's been in the arcade up to around 2005), it runs a bunch of other emulators including the Daphne laserdisc emulator, a pinball emulator, a Marvel Superheroes Mugen, and of course all the old console emulators: Pong, Atari, Intellivision, Nintendo, Super Nintendo, and some other sundries. It's mainly for MAME, though.
The control panel allows for four players, or alternatively the third and fourth player joysticks, which have top fire buttons, can be used for two player dual joystick games. For single player dual joystick games like Robotron you're going to want to use the classic balltops, of course. There's also two spinners and a trackball. And there's gas pedal and light gun attachments.
Min and i actually built something! We are reasonably proud. The Making Of page is coming soon.
