Debug Functions#

This page or section needs more images. There's a whole lotta words here, but not enough pictures. Please fix this. Specifically: Get screenshots of Free Player Movement Mode and Sound Test Mode if possible?

Several debug functions remain in the game. However, many of them don't work properly anymore, and the behavior of the sound test varies between emulators. After applying the code below, at the title screen, press D-Pad Down the number of times that corresponds to the desired function, then press A / Start to activate it. Pressing D-Pad Up will reset the counter just in case you lose track of how many button presses have been entered.

Free Camera Mode#

This mode allows you to move the camera freely around the arena.

Controls:

• A/B buttons to change player team/turn lights off.
• C buttons to change camera angle.
• Analog Stick to move camera around.
• L/R buttons to move camera up/down.

Free Player Movement Mode#

This mode allows you to move a player freely around the arena.

Controls:

• R to change camera angles.
• C-Down to win the Stanley Cup.
• Analog Stick to move the player around.
• C-Up to crash the game.

Debug Menu#

Unfortunately, nothing appears to work at all here.

Sound Test Mode#

Depending on the emulator you enter this mode with, it will either display a blank screen or messed-up text. It still sort of works, however.

Controls:

• D-Pad Down to change song.
• A to play song.

There are a lot of blank music ID slots in this menu. The first song is nineteen D-Pad Down presses.
