Things like the menu not displaying correctly with grayscale turned on

huh...
menus are not the most important in a game, are they ?

it also has stability issues

I've never had any problem with SMQ
(and I've played a lot with this game when I was in what french people call "Terminale" (before the BAC, the french equivalent of the english A-elevel, if i remember well))

and bannanas instead of coins

I'm becomming hungry
