Kirby's Adventure/Debug Rooms
This is a sub-page of Kirby's Adventure.To enter these rooms, use a code to change 0562-0563 to the room value of your choice. Then, enter any arena (the level 6 arena works best) and lose a life. You'll be taken to the room you specified after you die.
The main debug room! The first 5 doors from the left at the bottom lead to various testing rooms. The 6th and 7th doors don't work. The door at the top leads to the multilevel hub.
FUN FACT: The ladder pieces above each door actually represent binary numbers. Unsurprisingly, they're numbered (from left to right) 1-7.
Miniboss test rooms. Not just any minibosses, though -- these rooms have the faster, more difficult versions of Bugzzy, Poppy Bros. Sr., Rolling Turtle, and Mr. Tick Tock that are found in stage 7-2's hidden route. The scrambled backgrounds seem to indicate that some object definitions were changed after the room layouts were made.
Accessed from the main debug room, these are tests for the various Meta Knight battles in the game. The first five correspond to the Meta Knight room layouts that were used in the final game.
These rooms, however, weren't used. Meta Knight battles for the layouts of rooms #142 & #144 still exist in the game, but not for room #143.
