Shiren 1 SFC:Debug Mode

A debug menu.

Debug Mode is an unused mode in Mystery Dungeon 2: Shiren the Wanderer originally used by developers to test things in-game.

Accessing

Changing the bytes at 8000 and 8001 in a headerless ROM (or 8200 and 8201 in a headered ROM) from FF to 00 enables a slew of debugging functions (alternately, enter Pro Action Replay (PAR) codes C0800000, C0800100).

Functions

Controller 1 Functions:

• Start: Skip to the next floor and increase Shiren's level by 1.
• B+Start: Reveal locations of all monsters on the current floor.
• Y+Start: Reveal locations of all items on the current floor.
• B+Y+Start: Kill all monsters on the current floor.
• R+Start: Display full map of the current floor.
• B+R+Start: Opens a menu allowing the selection of any item in the game.

Works with the unofficial translation, however most of the text is unreadable.

• Y+R+Start: Turns off the background music. The only way to turn it back on is to reset.
• B+Y+R+Start: Opens a sound test menu.

Controller 2 Functions:

• Start: Allows for the entire current floor to be viewed using the D-Pad on controller 2. The coordinates of the portion currently on-screen are displayed, as well as map IDs and the type of the current tyle. The screen moves in tiles, which are 32 pixel each.
• Shift (held) makes the screen black.
• X: Displays Shiren's coordinates.
• Y: Opens a sprite and animations test menu including monsters, characters, and items:
  • A plays the animation.
  • B closes the menu.
  • Up/down to move up and down the cursor of the primary menu (monster select).
  • Left/right or X/Y to move up and down the cursor of the secondary menu (direction the monster is facing).
  • Start changes whether it plays the normal animation or an alternate one.

While in debug mode, if the player heads south of Valley Inn, the debug room can be accessed.
