Been playing a ton of Sega Model 2 games like Sega Rally, Daytona and Indy 500 on the driving cab I'm setting up. Crazy Taxi and Canonball too.

Cannonball is great, it's a full rewrite of Outrun but uses the original ROMs for graphics and a couple of other things. Try it if you haven't already.

You can turn the timer off so you get to see the full game and each different ending. I'd never seen 4 of the endings before, just the first one.
