MiiSX is an MSX 1/MSX 2/MSX 2+ emulator for the Nintendo Wii.

Based on fMSX-SDL, so far, it’s a pretty basic emulator. It doesn’t support either SCC, MSX Music or MSX Audio, only PSG.

Only uncompressed ROM files can be loaded, and there’s no keyboard implemented (so only games that work with joystick will be playable). PSG emulation is still problematic.


– The emulator can run MSX 1, MSX 2 and MSX 2+ games, in ROM format, from SD cards.
– SDHC supported
– Classic Controller and Wiimote supported, as joystick 1
– Basic menu, for selecting ROM file, and changing emulated system.
– Homebrew Channel compatible


SCC emulation (enabled or disabled with “-” on start menu)
PSG emulation without problems
Several optimizations
“X” on Classic Controller now emulates joy button 1+2, good for games like “Zanac” and “Aleste”
