Megadrive problem

[wariofer]

Megadrive II can run games from Megadrive I? It is that I 'll buy the Megadrive II with Sonic the Hedgehog 1 and 2 do not know if will run those games. sorry if this is a stupid question . I saw that the only differences were the headphone output and volume

They have the same compability as far as games are concerned. To simpify things a bit, the Megadrive 2 models generally have worse video and sound than model 1, but not to an huge degree,
