Super Monkey Ball 2/Debug Menu

This is a sub-page of Super Monkey Ball 2.

Main debug screen, which allows access to debugging elements.

Just like the first game, Super Monkey Ball 2 features a debug mode. The debug mode includes a stage selector, full-fledged model viewer, effects testing, sound player, bitmap reader, and more. The debug menu can be accessed via the following Action Replay codes:

Test mode, where the interesting stuff is.
Extremely early options menu, possibly a leftover from the Japanese Super Monkey Ball. The text is in Romaji with large spacing - which ends up causing problems. What's also interesting is that whenever you access the menu, it will play the Monkey Race 2 Expert Track music.
Author Mode, which allows you to access Story Mode cutscenes.
The Game Data screen when debug mode is enabled. References 'debug data', of which the purpose is currently unknown.
The success rate display on the North American version of the game. The data is only stored in memory, and is not actually saved to the save file on the North American version.

Test Mode

Images

Main screen of the Test Menu.
AV MODEL - This is a model viewer for viewing the various models found within the game.
NAOMI MODEL - This model viewer seems to only be able to view older resources that were leftover from Super Monkey Ball and even the arcade Monkey Ball.
PATTERN CHANGE - Appears to be a texture viewer. The options crash the game immediately.
BLUR - Motion blur testing.
SHADOW - Shadow testing.
FOCUS - Depth of Field effect testing. This has an option which allows the intensity and distance of the blur to be modified.
INDIRECT - Overlay testing. There is only one overlay viewable - the water effect from underwater levels.
DIP SWITCH - Allows for modification of DIP switches.
BITMAP - A basic bitmap viewer.
FONT - Views font sheets.
ROMFONT - Doesn't appear to do anything at all.
PREREND - This tests the prerendering of level images in Practice Mode.
INPUT - Tests controller input.
SOUND - Plays normal sound files.
ADX - This is a ADX sound player. Interestingly, all the ADX files included are used nowhere in the game.
REPLAY - Plays back replays made using the other debugging tools.
REPLAY SIZE CHECKER - Checks the average size of a replay file by testing it on each of the levels.
DIFFICULTY - A win/loss ratio chart - a carryover from both Super Monkey Ball and Monkey Ball. The percentage is displayed in the Japanese and European versions, but not in other versions of the game.

Early Options Menu

A very early version of the options menu is accessible through the main debug menu. It appears to be the version from Super Monkey Ball. The text is in Romaji (Japanese in Roman letters). However, since the SMB options menu was designed for English/Kanji, the Romaji breaks the layout and falls off the box or clutters up with other text. The options menu performs all the functions of the normal Super Monkey Ball options menu, except it doesn't load the old Replay manager because it was scrapped.

Gallery

Play Points screen. The Romaji overlaps the Play Point counter.
Ranking hub.
Interestingly, the ranking menu calls for the SMB2 rank screen even though the ranks are for SMB1 modes.
Sound settings.
Multiplayer screen settings.

Controller settings.
This is interesting. This setting saves debug information to a memory card. Unlike the rest of the settings, this is in English. The exact purpose of the Debug Data is unknown.

In-Game Commands

A few cheat commands are also enabled in-game:

Pressing D-Pad Up will add 100 seconds to the game's timer, with a maximum time of 360.96.
Pressing X + Y will instantly complete the current level.
The game can be debug paused with R + Start, which will display "DEBUG MODE" in the top right corner of the screen. Unpause with just Start.
Pressing Z while debug paused will advance the game by one frame.
Pressing L + Start brings up an in-game debug menu. Pressing L + Y closes it.
Pressing X + B while debug paused will display a cursor that allows you click on UI elements with X or A and move them around the screen with the Left Stick.
Pressing Y + B while debug paused will unlock the camera. Pressing again will reset it but it won't take affect until the game is unpaused. Unlocking the camera also disables the above cursor.
