Elite Advanced doesn't work here on my TekMagic (immediate freeze) nor does Zaxxon. The Alien Breed games seem OK. I've had few issues with WHDLoad on the Apollo, usually the "nocache" option takes care of it.
I think most of the incompatibilities are processor specific rather than accelerator type... the few problematic games on my Apollo 1260 give the exact same symptoms on the TekMagic.
*edit*
Changing the maxtransfer shouldn't mess your partition. If it does, you can always go back to the old value and recover any data.
