Bakukyuu Renpatsu! Super B-Daman

Debug Mode
Pro Action Replay code will replace the options menu with the game's debug mode.

The initial screen looks like a stage select, but "stage" in this context refers to individual screens/modes rather than stages. The A/B/X/Y buttons increase/decrease the screen number and Start enters the selected screen.

Valid screen numbers:
 * to : the same as the main menu items
 * : stage select
 * : file select
 * : bomb entry edit
 * : move type edit
 * : debug mode data
 * : sound test
 * : explosioin (sic) param

All other options are unnamed and return to the main menu when selected. Pressing either L or R will go to screen.

Stage Select
The actual stage select. This seems to only cover Challenge Mode, not Scenario Mode or Battle Mode. The controls are the same as the main debug menu.

Bomb Entry Edit
This screen allows you to edit the placement of bombs on each Challenge Mode stage.

Pressing A/B/X/Y increases/decreases the current stage number. Pressing Down switches to editing; from here, use the D-pad and A/B/X/Y to edit the parameters of each bomb (though what each one does is currently unknown.) Press L/R to increase/decrease the number of bombs in the stage.

Press Select to select a new stage to edit; pressing Select again from here returns to the debug menu.

Move Type Edit
This screen seems to be for editing the movement types of each bomb on a particular Challenge Mode stage.

Debug Mode Data
This screen is used to set/clear various flags and change the values at various RAM addresses (effects currently unknown). Pressing Start returns to the debug menu.

Sound Test
The sound test screen allows you to test sound. (Wow!)

Pressing Y/B increase/decrease the sound or music number, and B plays the selected music track or sound effect. Start returns to the debug menu.

Explosion Param Set
The last debug screen allows you to change the size and animation properties of the three types of explosions seen in the game.

"INIT", "END", and "ADD" are probably the initial and final explosion sizes and the speed of size increase; the other options are unknown.
