Applying the below code will enable a debug menu after pressing Start at the title screen.
USA Code: Debug Menu 002D2C28 000000?? 01 = Test Options 02 = Pad Test 04 = SFX Test 05 = Stage Select 07 = Debug Info 08 = ??? Debug 09 = Model Viewer 0A = Controller Config 0B = Mode Select 0C = Results 0E = Logos 11 = Push START Button
The only thing you can test on this menu is the analog sticks. Nothing shows up when pressing other buttons. Pressing Select will exit this menu.
This menu will keep track of how many times you want the track to loop for each specific ID. The ID being selected will also show next to PLAY NUM with the left digit being the ID and the right digit being how many times it'll loop. Using the D-Pad you can select some voice-overs and play them with Circle. Pressing Start will pause all sounds and pressing it again will resume where it left off. Pressing Select will exit this menu.
This menu would've let you select any Mission and/or Event in the game but all you can do is move the cursor with the D-Pad and exit with Select.
This will jump you straight into the game skipping the other menus and will display some debug numbers on the left-hand side of the screen. It is unknown what these values are for.
Not much is known about this menu but you can move Up or Down with the D-Pad to change stuff.
Use the D-Pad to move the camera, use L1 and R1 to zoom-out and in, respectively. L2 will reset the camera. Pressing X will display the model in wireframe mode and pressing it again will return to normal. Pressing Square will display a red graphline and will allow you to scale the model with the D-Pad as long as it's held down. Pressing Start will open a menu, which will allow you to change models.
Use Left or Right on the D-Pad to select a controller configuration. Press Select to exit.
This seems to be a cutscene viewer of some sorts. Use the D-Pad to select a No. and press Circle to view one of the cutscenes. You can also go back to the menu by pressing Start during a cutscene. Pressing Select to exit while a cutscene was playing will crash the game.
Can't do anything in this menu except exit with Select.
Shows the logos from bootup.
Push START Button
Goes back to title.
