i tried to play this marvellous game.
I have a tapuino for my PET 2001. The PET have a RAM expanson, it have 32 KB RAM. i was converted the .prg files to .tap from this description:
Commodore PET loads .tap WAV files - Retro computer collector - vintage computer collection (retrocomputerverzamelaar.nl)
The programs (your other games) load correctly, but all of them sent an error, illegal quantity error and similar.
Don't you have your own .tap versions, what can i try to load my PET?
Thanks!
