This Dreamcast pack has lots of classic AM2 sprite scaller games on. It has the original Outrun, but more importantly it has Power Drift. The rollercoater bonkers mad racing game is hard as nails, but a blast once you get it. Also this pack has Hang on it which is some nice simple fun.
Also if you can find yourself a Scud Race ROM to play on

Fighting
