Well, as I said in the corresponding games' threat, a software slowdown will do, I just DLed the windows version (because it's so goddamn awfully slow in DosBox) and I use
THIS nice little proggy here in addition... Just scroll down a little and click on "Download starten".
Works fine for me.
The clou is, if you slowed it down completely and the game is still running too fast on your PC, you can open it a second time etc...

EDIT @ Anubis: Sorry, but the Sega-version sucks donkeys' balls in comparision... the GFX are just awful. And that's coming from a rabid Sega Genesis-fan
