I managed to successfully unlock my G&W firmware using an STM32 programmer.

Once unlocked, it's possible to compile and flash a port of the retro-go emulator collection and a handful of roms.

The emulation is surprisingly good, making the games fully playable at 60fps with sound.

Currently supports Game Boy, NES, SMS and Game Gear.

The G&W only has 1MB of storage available, but it's possible to solder a 16MB replacement instead which should allow for a good selection of roms.

Be very careful de-soldering the SPI flash chip as it's easy to lift pads and break traces. Then solder in the new 16MB chip.

Now when you re-flash the chip you can fit all the larger roms easily.. 16MB is a lot for NES games, mine isn't even half full with 24.

** All credit to stacksmashing for figuring out how to break the device open, and kbeckmann for porting the emulator.
