Both versions of the game use a PlayStation 2 emulator to run the game. Otherwise, I'm wondering if there's much of a difference between the PS3 and PS4 versions of this game. I know the original PS2 version had some issues when compared to the GCN original. From what I've seen reported however, the PS4 version sorts some of these issues out (e.g. reduced load times). Otherwise, does anyone have any personal experience with either version of the game?
