I will say though, it forcing special battles to 6 Pokemon causes really... interesting stuff to happen with Double battles. As in, I hadn't modified my files yet from last build to take into account the fix for the bug, and I got into a fight with Jesse and James.
They had, in total, 12 Pokemon. I guess Team Rocket really doesn't fight fair. (Probably a bug, seems to just be a side effect of the double battle combining the party of two trainers instead of being seen as one battle. Avoidable by just not having 6 in both.)
And the HighPowered move thing still gave the same error, but at that point I think it's probably just me doing something wrong.
