There graphical changes mostly so far with Skin and Hair except for Relm, so far. Only minor text changes have occured, the characters default names (Terra -> Lisa

) and the likes of
Fenix Down -> Phoenix Down
Pearl -> Holy
Mad Oscar -> Malboro
Revifify -> Holy Water
I changed the originals to what they should be but Nintendo of America changed them because of their stupid censoring or to what they have changed to in later games (Malboro is one of those)
Because each emulator is different I cant provide controls. But if you are going to use ZSNES, then the contols will be
SNES -> PC
A = Z (Enter)
B = X (Cancel)
Y = A (Change Party in Multi-Party events)
X = S (Menu)
L = D (Next Character / Multi Target)
R = C (Next Character)
and the arrow keys are the D-Pad
