Newbie Still Doesn't Understand Code

I'm just working with C3 for this example, so I'm just looking at the "outside of battle menu." But I was able to cast the eligible spells from the menu and they worked as they normally would.

I'll try on another emulator to just confirm it wasn't just the one I was using, but it DID work.

Edit: I did try with both a different emulator and a fresh local copy where I made the changes. I can confirm the spells are usable from the menu.



Magic list displays as normal, but when you press Y...


SUCCESS!!  Let's repeat.



Again with no Y...no spell...but press Y...



...and the spell is added to the list! (Note, the 0 in MP cost is displayed if the cursor does not move, but if you move the cursor, the correct cost is displayed. This part IS buggy, though.)

Yes, the spells work...




What I was trying to do was figure out how to get the list of spells to appear without pressing Y, and while I can do that by removing the branch...that forces the MP cost to be displayed all the time. I can live with it, though, and I might figure it out myself. I'm taking baby steps here.

And speaking of baby steps, just blanking C3/4FE0 and C3/4FE2 has no effect while blanking C3/4FE7 and C3/4FE9 seems to have the same effect as described, which indicates the latter code is responsible.
