I just looked at this game (for about 1 hour!) and I got absolutely nowhere

I set breakpoints all over the place, and nothing. Kwap

The reason I'm having trouble is, it's a DOS game. I don't want to resort to having to learn the Amiga's OS until I master NDOS and the like.

Anyway. Let me tell ya what I tried, and you can tell me what I'm doing wrong

First. I tried to break on any access of the "Consult the color chart" message. This would allow me to see where it starts the protection.....but it didn't break

And then....I decided to try to break on any access of the number we're supposed to look up in the manual, but this number kept jumping around in memory

And then....I decided to try to break on any access to the actual colours (even though they're probably part of the Consult the color" thingy)....but it didn't break

And then....I decided to search for any instructions that would maybe load the addresses of ANY of these.....And I found none

And then.....No and then!

Actually, after that I decided to start mucking around with PAL/NTSC switching, but my experiments went horribly wrong (this has nothing to do with the game btw)

C00000 move.b #0,$dff1dc ; Switch to NTSC....Works fine
C00008 jmp $c00000

While in NTSC

C00000 move.b #32,$dff1dc ; Supposed to switch to PAL...Didn't work
C00008 jmp $c00000 ; Is it cause I'm on KS1.3?
