The Arcade EMU for the Wii, SDL MAME, has been updated.
How to use
Unzip onto your SD card/USB drive.
Changelog:
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
