if it was that easy to "patch" OS4 to run on a PPC based Mac, dont you think there would have been someone that would have accomplished this by now?
if Hyperion was smart they would have released this for the PPC Mac a long time ago. Would there be more AmigaOS users had this decision been made? You tell me how many OS4 users there are now + Classic OS4.. then think of how many PPC Macs there are available. You do the math. Its common sense, but in the Amiga world there is no such thing.
