Is it even possible to restore the original menu columns to american FFVI?

I think you asked before that question on the Discord server and got your answer.. Yes it's possible and I think it was already done somewhere.. Now are you looking for someone to do it for you or are you willing to learn what is required to make that hack? If it's the latter you'll need to learn some ASM hacking. For the menu documentation bank $C3 is fully documented.

Maybe both, if someone wouldn't have the task to do it, i'm going to try to do it by myself
