How about seeing if a POKE to what would be a mirrored I/O location on a 64
(and decoded on a 128) shows up in the "regular" location?
e.g.:
mode=128:poke[I/O location],x:poke[mirrored location],y:if peek[I/O
location]=y then mode=64
Unfortunately, I don't have my P.R.G. here, so I don't know which address
might be suitable.
