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:

– Compiled with libogc 1.8.6, USB loading should be faster now if you have IOS58
– Changed video code around. Most games get a speedup or remain the same from this, but at least one (frogger) is slower for some reason.
– Widescreen support
– Fixed some games giving duplication errors and causing the emulator to exit
