This might be worth reconsidering. I'm reminded about the recent ruling regarding starting from save states. In this case, allowing the use of a modified ROM opens the door to there having been some kind of other modification that would give an unfair advantage. Of course, there's nothing stopping people from trying to do that with the original Japanese ROM, and I've seen a few speed games that allow runners to use cosmetic mods in their runs. I'd personally like to be able to run the games in English too, but I thought I should call this out early on.
Who knows, maybe it will come out at some point that the English patch also fixes a bug that changes gameplay slightly, or maybe text loads faster on that version. I'm not saying it does, just that allowing things like this opens up this sort of vulnerability in the future.
