You actually put your own CPU in the pod, but I think they have a "max" rate
too. One thing that *might* be an issue is if the pod introduces any
additional propogation delay to the signals. Since some games are just
under the wire anyway (remember those internal Atari memo's I put up a
couple years ago about changing certain parts to S instead of LS series to
shave a few nanoseconds for some timing violations?) with respect to timing
maybe the additional delays are enough to mess some stuff up.

I've run it with stock 6502's before. Star Wars also runs dandy with all
the 68A09EP's I tried too. Just overclocking for the 1980's. ;-)
