hello people, i got a copy of this game about 25 years ago and to this day i cant beat it, reason being its got some corrupt tracks on the disc, ive tried getting another copy (infact ive tried all over the net) and they all seem to be corrupt, has anyone got a working image or even the original, it was made by GM Software, coded by Kai Foerst and Uwe kall

any help would be smashin, cheers tim.
