Well,
This game has plenty of covers, yes the NTSC/J, the NTSC/U-C, and also have you check the Europe ones? There are many of them...
So I think, since this game has so many covers already, I dont think it worths make a custom of it, even it that is taking best part of each to make a custom mixed of original parts...
Thats my opinion, but stills check the Europe covers for this game, u may get pleased.
