I was coming to delete my message because I was able to use Unarchiver to extract it. I thought it wouldn't work since it doesn't say anything about running under apple silicon. I haven't tried playing the game yet. I had been trying to get emulators up and running on the M2 mini so I if I wanted to I could get rid of my G4 PowerMac. Two nights ago the G4 went on the blink which may have made that decision for me.
Thanks for replying.
