How it works...

MAME4All is a Multi Arcade Machine Emulator that takes advantage of the Raspberry Pi's GPU to achieve very fast emulation of arcade machines. It is able to achieve this speed by compiling with DispManX, which offloads SDL code to the graphics core via OpenGL ES. When you run MAME4All, it looks for any game files you have in the roms directory and displays them in a menu for you to select from. If it doesn't find any files, it exits after a few seconds.

The default keys for MAME4All-Pi are:

• 5 for inserting coins
• 1 for player 1 to start
• Arrow keys for player 1 joystick controls
• Ctrl, Alt, space bar, Z, X, and C for default action keys

You can modify the MAME4All configuration by editing the /usr/local/bin/indiecity/InstalledApps/mame4all_pi/Full/mame.cfg file.
