So, I've been trying to do a very simple texture swap in the PreCure video game. It's just an edit of one of the result screens. Using Wiimm's tools (and SZS Modifier subsequentially) I have successfully managed to pick apart the arc, convert the tpl, edit it, convert it back, and stitch the game back up into an ISO. (Loading with USB Loader GX) Inside the arc there were 3 different tpls, I only touched one; the two I didn't touch still appear just fine. Much to my chagrin, however, my modified tpl will not appear. At all. It's absent. I've checked with SZS modifier, the new tpl is the correct image format and size, so why?
