Genesis extension causes errant region detection #13

I've noticed that using load_rom for Genesis games will sometimes fail, since the rom link will use the .gen extension, causing the core to assume a U.S. release, which won't work for certain .bin or .md ROMs. Maybe the easiest solution would be to have separate "systems" for the three regions, each with their own specific extension?

I did not know that the region detection was (in some cases?) based on the file extension. However I split the megadrive in 3 system: GENESIS for .gen, MEGADRIVE for .md, and MEGADRIVE.BIN for .bin.

Nice, thanks! (And thanks so much for creating this project, btw.)
