You've hit a sore point :-(.
There IS a PPC mac emulator(FusionPPC), works nicely with OS9.1 I think. The catch is it only work on CyberstormPPC cards: A3000&A4000 only! :-/.
A Blizzard version was promised (I even preordered FusionPPC with 3 other guys). But it never came...
So the best you can do with an A1200 is 68k/MacOS 8.x era stuff. There are 2 main 68k mac emulators: Fusion and ShapeShifter. ShapeShifter is freeware nowadays I think, don't know what the status of Fusion is.
Hope this helps.
