SDL MAME Wii is an Arcade Emulator based on SDLMAME. Many games for early arcade boards can be played with varying amounts of success.

Changes:

Downgraded to MAME 0.134u4 due to issues with some ROMs not working
SDL no longer used for video; FPS is increased
WiiMote Sensor support more stable
Fixed default font being too small; the custom font has been removed
