Apple IIc Plus & Karateka

Hi there

I have three Apple IIc Plus machines, and while Karateka runs, the graphics in game is corrupt and unplayable. The sake disc plays on an Apple IIe Platinum. 

This happens across all three of the Apple IIc Plus that I have, so they can't all be fault.

I am guessing there is a version of Karateka that will work on the IIc plus or perhaps not.

Anyone else come across this with that game?

Other games I have tested work well.

Thank you.

Francesco
