Yeah, I thought of that. The only thing is since ROM hacking in items would be a pain (I'm not sure if I would even be able to use the savestate I have now if I change the ISO a bit, not to mention transferring files between my computer and VM to edit and reparse the ISO is like a 2-3 hour ordeal), I would have to resort to RAM hacking, which would require me to bug SoC again and I don't want to do that since he's a pretty busy guy and he's already helped me with a TON of stuff (besides, he already walked me through the process of trying to find character data in the RAM and it sounds almost impossible).
I could always try using one of the Gecko codes (at least for reference to find a character's address) to hack in a couple scrolls, but I'm having enough issues with codes as it is and I'm not too hopeful that that would work anyway.
So yeah, I'll give it a shot in a while, but right now getting the chapter end code to work again is my priority. After that, I'll try adding in scrolls using at least the RAM method (and possibly the ROM method depending on how much time I have), but if those don't work I'll have to decide between keeping future characters alive long enough to nab their scrolls (won't be able to get Sothe's guard and renewal or whatever meg has this way) or just keeping the rule the way it is now with skills banned.
TL;DR: It's a possibility and I'll try a couple things that come to mind, but I wouldn't get my hopes up.
