Debug menu (SSBM)/DEVELOP mode

This article is about the usage of DEVELOP mode in Melee. For a collection of images of each stage under the effects of DEVELOP mode, see Debug menu (SSBM)/Stage data.

Melee when run in DEVELOP mode.

DEVELOP mode is a debug mode found in Super Smash Bros. Melee accessed through its debug menu. The mode is activated by changing the DBLEVEL setting to DEVELOP. This will give the player extra control over matches, including free camera, visual hitbox, and frame advance.

Below is a table detailing the controls for the DEVELOP mode extra controls. Through these controls, one can obtain free control over the camera, see character and stage hitboxes, frame advance the match, see the parts of the stage, and drop items (similar to Training Mode). Using the "reset" button combination in Classic Mode, Adventure Mode, or All-Star Mode results in a "stage clear".
