OK, lemme try to overtop this one even!
It could be that (thanks to a discussion starting from usenet) I found another game that only works on KS 1.1!
Try it yourself!
( => zone)
With either 1.2 or 1.3, you can merely do one move, then the game will freeze up!
Has also been tested on the real thing.
1.1 (PAL) works!
