SOTB will work from floppy with an A1200 or A600, it's just a question of the right Degrader settings and how much time you want to spend messing with it. I used to write this stuff down somewhere, I'll see if I can find how I did it.
IIRC the only old game I was never able to get working on the A1200 was Megafortress... dunno why, but no amount of tweaking would do it. Must be one of those badly coded "68000 only" games Piru was talking about the other day.
