Debug Menu

This is a sub-page of Mother 3.

This needs some investigation.
Discuss ideas and findings on the talk page.
Specifically:

Investigate the effects of each control. Some seem to do nothing.
See if the battle debug menu can be accessed similarly.
I've ran into a glitch a few times where using the debug menu makes the battles just a black screen, though outside of that they still function properly. This happening seems to be inconsistent. Can someone investigate this?

MOTHER 3 has two unique debug menus, one for the overworld and one for battles. The overworld debug menu can be accessed with the following steps:

Set a breakpoint at 08039B88
Enter a new room and when triggered, set PC to 08039C04
Allow the room to finish loading and set 02005C00 to 0F

Alternatively, you can download one of these patches by Lorenzooone below. The debug menu is activated in these patches by holding START and SELECT while loading a room, most easily done by entering a menu and then exiting it. Note that you can switch between moving in the overworld and using the debug menu by pressing R and L, but this was added in the patches and are NOT part of the original menu. The English version of the patch must be patched onto a ROM patched with version 1.3 of the English Fan Translation.
