Couple of differences from other versions so far.
The "max stats" and "autosave" options are in the config menu. There's an option at the bottom of the screen at all times to turn encounters on and off. Cloud runs by default, and the dialogue where Barret tells you how to run (that bit about holding X) is changed to "hold the directional buttons while holding to walk".
The opening FMV was really surprisingly laggy. Gameplay is pretty smooth and everything looks good so far. I hate the controls but they're at least functional.
EDIT: There's no in-game option to quit under save. So there are a few menu changes so far from the PC version.
Next to the "Encounters On/Off" button there's a button to change from analogue to digital controls, but this switches automatically to digital in menus and battles (which is helpful). "Analogue" controls is that in name only though, since the movement is still the same 8-directional we're used to. I don't have time to play much more right now since I'm off to bed, but I'm intrigued. The game looks good on a small screen, especially the text since this is a port of the PC version. Thankfully it doesn't have the horrible PC MIDI.
