Is their way to remove wall kick patch only codes instead of backing up.My released ROM hack: Yoshi Saves Summer Vacation
I posted this in Discord last night not sure if you saw it or not you pretty much have 2 options one follow this tutorial which may or may not work or two port your hack to a new rom without the wall kick patch which would be safer.
Someone might have another option but those are the only 2 I know of myself.
