Debug Rom

Debug ROM

The Debug ROM is an early build of the game, which has a lot of extra functionality. Its main purpose in Speedrunning is easy practising - especially on console - and to run New Game+ categories.

Controls

One day, Ckosmick shared some "Forbidden Knowledge" with us on the Community Discord Server.

Debug Config Screen

The Debug Config screen appears immediately after loading the ROM. If you want to return to that screen later, press Start + Select + A + B.

Enable/Disable Room Transitions
1. Go to "etc."
2. Set the value of "ゲートコウカ" to on/off

Spawn at a specific location
1. Go to "SECTION"
2. Move the arrow cursor to the location you want to go to.
3. Press "Select".
4. The map of the area will appear. A white square will indicate the location you will spawn in if you press "A". 
   In the top right corner are the "h/g" coordinates of the room.
   H = Heya = room number
   G = Gate = door number
   Note: You will always spawn at a door in the room you have chosen.

Pausing

• Start = Pauses the game with the Debug Menu accessible.
• Start + Select = Pauses the game and replaces the Debug Menu with the status screen
• Select + L in a pause screen = Icons appear in the top right corner of the screen
  • Samus Icon = current room number
  • ➡️= X coordinate (0 = left)
  • ⬇️= Y coordinate (0 = top)

Debug Menu Screen

You can open the Menu Screen by loading into an area, press Start and press R (see "Pausing" and "Debug Config Screen" sections).

Toggle events flags:
Press "Select" in the Debug Menu Screen = opens up the Event list. Events can be toggled on/off by pressing "A".
A list of all event flags can be found further down below.

Reading the top row of the Debug screen:
- AREA: 3-letter acronym of the area you are in. For the test areas, it is TN1/2/3
- HEYA: Number of the "Room" you are currently in. (HEYA = "Room" in Japanese)
- GATE: Door

Sound Test:
Go to the topmost right tile next to the numbers of "GATE" and press "A" to play a short sound.

Noclipping

• L + B + Start = Enable Noclip
• Select = Disable Scrolling during Noclip
• B = Cancel Noclip
