It seems to be an unfinished world that the dev team scrapped, not sure why exactly. I don't think you can get there playing the game normally. Lots of stuff isn't complete in it, like the door doesn't animate when you open it, it just disappears, and there's no boss. It' just a bunch of individual stages chained together with no exit, like on Bagura's Battleship, you just keep exiting doors. When you exit the last door the game just freezes up.

It seem like you have to beat the final boss within an impossible time limit, when I heard about this the guy got there by accident using PAR codes to adjust the time limits and stuff. I'm guessing this was the dev team's way of dummying it out without going in and deleting code.

So what you're saying is, you have solid evidence to prove that cheaters do in fact go to hell.
