BTW I tried Rick Dangerous 1 and 2 on the TT - the first one works out of the box here, but the 2nd has a slight problem that's due to the TT's MMU, I fixed it on the spot.

My TT has TOS 3.06de, what's your version?

Oh yeah, now that I remembered it, try running rick1 from a floppy with a completely clean boot (even bypass the hard disk driver - holt alt after the memory test).

Let's get you to run rick1 properly and we'll work on fixing the rest then :)
