I'm not sure how retroarch decides what the name of a game is, but it's showing up in my catalog as "Final Fantasy Tactics" instead of Dissidia013, which sucks since I have basic FFT in the same catalog. Dunno if that's an easy fix or not (how does the CD know the name of the game on it?). Regardless, gonna dive in now.
EDIT: I appear to be having sprite issues. I thought it was just related to the intro battle (where I had Ramza, 2 gafgarion sprites for some odd reason, plus the usual agrias and apparently a malak), but going into the first battle I'm still not getting edited sprites at all. I have Wakka, Lulu, and Squall by name with the appropriate abilities and the game hasn't crashed, so it seems to have patched. The sprites it's using are Ramza's, Olan's, and ...I don't remember. She has a ponytail and a cape. The patch I used was the one in the previous post, not the one in the initial post.
