Am I to understand that in the PSP port that it is impossible to change the sprites of characters that appear in the roster and battle formation screens?
That although one can have a unique character in actual battles, when it comes to fiddling with changing jobs and looking at the party roster or the pre-battle roster set-up, the sprites will just appear as buggy messed up sprites?
Is that correct?
Partially.
If the job has a roster screen sprite normally like generic classes, the special classes that you get normally (guest and permanent) and certain NPCs that for some unknown reason just have a formation screen sprite (Valmafra, Simon, etc.) then you can change the way they look in the formation screen and roster.
If they don't have a linked roster screen sprite like the majority of NPCs then you cant do anything.
