How do I delete all these unwanted sprites?

[uncutpokemon]

I was trying to change the sprite of oak in the intro, but not only did it fail to change the way I wanted it, it also created a bunch of these unwanted extra copies of the sprites. As a result I can't load the game because I get a message that says "Unsupported ARM mode 19" popup infinitely (I have to force close it to make it stop). Since I'm certain that it's because of al these unwanted oak sprites, how do I remove them from the game?

Though I am utterly nonplussed at what happened here, I can say that you should be using unLZ.gba to add the intro sprites, and then edit the pallete of the respected sprites using APE.
