Thought I'd mention some stuff:
It does fit larger screens! It's pretty good looking too.
The hidden Music / Sound Test can still be accessed by making Ramza's name PolkaPolka while starting a new game.
Edit: Beat Orbonne, you can skip scenes which is nice. The movies play really well and at a normal pace, the battles are a little off though. The speed at which different effects, attacks and camera movements play are all a little off from each other, which can be a bit strange. But over all, it seems to run fine. Especially considering that this tablet I'm using isn't exactly high end (or new).
Edit 2.0: Changing jobs is hilarious because it reverts the sprite back to it's pixelated form (why store them at all if you just use the updated graphics 99% of the time???), then it flashes back into high def once the transformation is done.
Menu's open painfully slowly and I think that's the main thing holding this games speed back.
2 days later: Random battle music can randomly be the unused music that is a mix of the song that plays during randoms / the song that plays when you fight Meliadoul. I have no idea what any of them are called, but I know that that particular song is never used in Vanilla and I'm 99% not in PSP WoTL either.
