wow, if you two idiots could read - there is alink to mushroom kingdom. The 'prototype' is an inbetween stage BETWEEN doki doki and the US released version. Get your heads out of your rears and read.
BULLSHIT Doki Doki panic was a game in its own right before nintendo renamed it Super Mario 2 in the states. All the characters were the same, the spirits were changed, but the game is 1:1 Nintendo thought the real Super mario2 was "too hard" for American audiences. These same people thought SuperPacMan was the natural successor to pacman. If you ever played it, you know its lame as shit

According to the Mushroom Kingdom link, this isn't DDP or SMB2. This is something in between, a true prototype cart. That's an incredibly rare find.
