While this might put the cat amongst the pigeons - the Megadrive is clearly the definitive version of this game. In fact if memory serves this is the system it was designed for. But my good friends fear not, at the end of the day the Megadrive is a cost reduced A500
Totally agree. Flashback is my favourite game of all time and I have played most versions but the Megadrive is the definitive one to me. It has the best music, original sprites (some were changed in other versions) and lacks the dodgy CGI and voice acting of later ports.
