Today, the first version of MSX Advance, an MSX emulator for Gameboy Advance was released. The emulator is already capable of running several MSX1 games quite decently.
I've just tried, and I am amazed on how many games it runs! Magical Tree, Thexder, Antartic Adventure, Elevator Action, Ping Pong, Castle... the list goes on and on...!
The only "glitch" I found was on Nemesis, which ran too fast
Awesome!
