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).
