All Codemaster games use special cartridge mapper that is not implemented in MD Everdrive.I can't get Micro Machines for the SMS working on the MD Everdrive cart. I just get a flashing blue screen. I've tested on two North American Sega Genesis systems (model 1 and 2) and a CDX. Any help would be appreciated, as this is a favourite of mine!
Also, I think this game makes use of extended video mode that is not supported by Mega Drive hardware, only display correctly on Master System last revisions.
