I'll start by saying that I have some experience in pure programming, but I'm not entirely familiar with all the Amiga hardware variants.
That said, I've tested the game on my real A1200 and on various emulated machines, such as the basic A500 (only 512KB of Chip RAM) and the A600 itself (with 1MB of Chip RAM), and it works perfectly.
It's really difficult to figure out where the problem might be. Could you tell me if the game crashes immediately after loading or if it happens later? Could you give me the Guru Meditation code?
