Have you ever felt the urge to play MSX games while on the road? Well, you could of course run an MSX emulator on your smartphone, but thanks to a recent development in Japan you can now do it in a more retrogaming fashion (or should we say hipster?) with the GGMSX adapter. This extension to the Sega Game Gear makes it possible to play MSX1 cartridge games directly on the Game Gear. The result? See for yourself!

For further details, there is an interesting topic on SMSpower
