Here is what i know.
1) pauline pace program is undetectable. it is an advantage, but we can't possibly know.
2) pace rom supposedly doesn't affect gameplay.
therefore there should be no difference between the two.
Therefore a test. record an imp on one, and play it back on the other. it should sync, if the two are truly identical.
if playback syncs between the two, then there is no change, and it should be allowed. if it dos not sync, then it dose affect gameplay, and scores with it are not comparable to pauline assisted scores.
If it does sync, then it's possible to just convert the inp and play it back without pace anyway, making it just as undetectable.
Sorry for being late to the party.
