Any home made version made will be hit by this asswipe with a copyright lawsuit. I wouldn't even bother.
The legendary status of this game is a big joke at this point. People need to let go and forget about it, the collective energy should be put in much more interesting projects, like all the new games that are popping up here and there. Supporrt should be given to REAL Amiga projects, by REAL Amiga enthusiasts, and not to fuckwits like Mark Cale.
Fuck Mark Cale, fuck System 3 and fuck Putty Squad.
