Clawgrip just dumped my Mega Key 2 cartridge, which is a region free converter for the Mega Drive/Genesis.

not really sure how you emulate that. I guess it's similar to the TMSS workarounds some pirate carts use (a PAL that puts certain signals on the bus to trick it)

there's no 68k code or anything in there at least, so unless you emulate at signal level, not sure there is much we can do with this.

Depends how it's wired. It might check for the address of the region byte in the header and supply something else, which we could emulate. And then it'd be another step in the Sega Stack of Doom.
