I was looking for a way to include all 5 versions of the Game Gear Micro on one single GG Micro.
I found a guide some time ago on an italian site for those interested:
retrofixer.it
problem is that the required file, a modified "nandd" that include all GG Micro version (black, red, yellow, blue and white) can't be found anywhere.
So that's why I am asking here, anyone has any clue about where to find this file or how to create it?
Thank you
