Maybe I will some day, to see how well it stacks up to the original. Hopefully there's a game shark code, as I've never been a fan of DK games past the NES era.
You have to go through a level to unlock it. It's not selectable from the title screen IIRC. So even if you unlocked it, you'd need codes to unlock the level it's in and the abilities needed to make it that far.
