The state of OS9 emulation is pretty bad. The best that i've seen was sheep shaver and even then lots of problems. Very sad. Compatibility mode on OS X is also a fairly poor solution. Then again, classic MacOS was a pile of crap anyway. Lots of fun playing the old games though. Best to get your hands on the fastest machine you can find that will run OS9 natively. The old macs (and the new ones) seem to last forever.
