On the settings I have my emulator on, I've never experienced slowdown. However, without changing any of my settings, I have begun getting quite a bit of slowdown during spell animations.
In addition, small text errors have begun popping up: Any instance of "ni" in "Knight" is shown as some Japanese symbol in battle (which has never happened before), and after the battle it trasnsfers over to the save screen. Even after saving, said replacement doesn't carry over after a reset until I get into a battle. Also, Ramza's skillset shows up as "Guts" in battle (and only in battle) despite having renamed all its instances in TacText.
I thought these errors may have been a result of increasing the palette and spritesheet limit, but after reverting that with a clean BATTLE.BIN, the problems persist.
EDIT: Okay, the clean BATTLE.BIN explains Ramza's skillset being called "Guts".
EDIT: And the messed up "Knight", too. I guess due to DTE. As for slowdown, I guess I'll restart my computer and see what happens.
EDIT: The slowdown persists. Though I guess it probably doesn't have anything to do with the changes I made to the iso. Why can't I come up with answers before I ask questions?
If I want to change join Mustadio's formation sprite/portrait to that of another character's (the mage girl person, in this case), while keeping his guest version using his own formation sprite/portrait, could it be done?
EDIT: Okay, I've mostly got it. But now Mustadio's palette seems to be messed up, and I can't figure out how to fix it.
And also his portrait in the Brave Story is wrong. Where is it located?
EDIT2: Okay, palette is fixed. I still don't know where his Brave Story portrait is located, though.
