@jbuente I got this game to run from a non-merged mame 0.78 rom pack, indytemp.zip, 352kb. I think you may be using a rom from a merged rom pack, as the errors seem to indicate mame is looking for parent/children roms. Before I eventually found it from the non-merged pack, I was using the German version. It works perfectly, other than the spelling is in German.

@arcadez2003 i see, thx for Info. My Problem is that i cant stop once i have speed and the whole game becomes terrible hectic. But maybe i just have to practice 😉
