Debug Menus

This is a sub-page of Proto:Kirby & the Amazing Mirror.

There a few screens used for debugging left in the game, although they require patches to be activated, since no caller exists for these functions. They were removed almost entirely from the final game.

Sprite Test#

This screen is used to display sprites and animations. A sprite is referred to as "CHARACTER" here, and each one has one or more animations, called "PATTERNS".
Ooooooo SCARY floating Kirby. The menu lists various controls:

RIGHT & LEFT: Scroll through CHARACTERS.
UP & DOWN: Scroll through PATTERNS.
A BUTTON: Replays a PATTERN.
START: Pauses an animation at any point.
SELECT: Slows down the PATTERN that's currently playing by alternating between pausing and playing.
B BUTTON: It's supposed to make you exit the menu, but it instead boots you to a blank screen.

Oooooo SCARY Fire hat apparition.

There are also more debugging options not mentioned in the screen:

A + ANY DIRECTION: Move the sprite on the right.
A + SELECT: Makes the sprite on the left to disappear.
A + START: Makes the sprite on the left to gain Fire's hat.
L/R: Scroll through the sprites faster.

Error Handler#

This needs some investigation.
Discuss ideas and findings on the talk page.
Specifically: Figure out these sets of 4 entries, possibly related to 4-player multiplayer.

An error handler shows a screen with text about a communication error, officially localized as "Communication Error! Check all connections and try again". 4 sets of entries appear on-screen. Error codes can be found starting at address 08717124:

ERR_NONE
ERR_SENDRECV
ERR_KEY_SIO
ERR_KEY_NOTKEYPACKET
ERR_KEY_CONNECTID
ERR_KEY_ENDBUF
ERR_KEY_INVALIDKEY
ERR_KEY_MAXSKIP
ERR_KEY_CHECKSUM
ERR_KEY_DELTAOVER
ERR_KEY_???
