I wonder about the probability of using something like IRA to disassenble the code, then go through it and document the Atari ST hardware registers and ROM calls (so it's easier to know when trying to re-code it for Amiga), then trying to recompile it afterwards. After all, if you do a straight 68000 re-assembly, but change all the hardware registers/ROM calls etc. to what the Amiga hardware uses - surely the code should work? It won't be as fast as an optimised Amiga version using the Blitter etc. but it should still work (in theory). Hence attempting some relatively simple game (like an RPG) would have to be better as a first attempt, as you shouldn't be worrying too much about timing, interrupts etc. as you would be with an arcade game.
It wouldn';t work like that!
Large portions of the game will need to be recoded as the amiga handles the display/sprites/sound etc differently to the ST!!
It is actually a difficult job converting to the amiga from st... Main game would work okay as the ST will use the same cpu registers as the amiga etc.. but rom calls and system specific stuff will definately need recoding.
