It is likely that the game requier ROM1.3 , the A600 comes with ROM2.0 and so it could need a degrader software like the A1200 had (ROM3.0). The good thing about the A600 is that you can use a kickstart switch with it so you could actually have both ROM's in the machine... 2.0 for workbench and games and 1.3 for those games that refuce to work on 2.0.
