Huh, I never knew that. Is that something we should take into account while mashing or is it something that would only affect a TAS or turbo user?
Yeah, it's okay, as long as the only modification to the game is the fan translation.
You can filter the leaderboard so that only English runs show up. I don't know why they don't show up by default. You'll have to talk to VB about that. But yeah, it pretty much counts as a different category.
For NG+ runs you can have anything as long as you can get it in a normal playthrough. For example, you can't give Salsa stuff you can only get in Chapter 8, but anything up through Tanetane Island is okay. Level doesn't carry over, and neither does equipment for anyone but Salsa, Lucas in the first Mole Cricket fight, and Duster in the Reconstructed Caribou fight (headgear only). Lucas and Kumatora should have every PSI ability they learn, but you don't need to go past level 60 for that.
