DebugIcon.png This game has debugging material.

To do:
  • A file called "DUMMY" in the root DVD folder has 125MBs of music. Check and see what this is.
  • Enable the other debug functions (USA RAM addresses):
    • 0x00205620 gmDebug2
    • 0x00207d38 gmDebug3
    • 0x002e9670 ariDebug
    • 0x0023c1d0 onoDebug

Dual Hearts is a rather obscure game for the PlayStation 2 that probably would have remained Japanese-exclusive had Atlus not stepped in and gave it a North American release.

Debug Modes

A few debug modes left in the game can be enabled with the use of codes. Apply the code below and use Controller 2 inputs to activate the menu.

With the code on, press the following buttons on Controller 2 during gameplay:

  • L1 + R1 + R2 + L2 - Unknown. Presumably does something weapon-related.
  • L3 - Displays an effect above the player's head. It appears it has another effect as well, but it is unclear.
  • R3 - Enable/disable debug menu.
  • Square / Circle - Changes debug pages when the debug menu is enabled.
  • D-Pad Left + Select - Change debug mode to 0 (regular menu).
  • D-Pad Right + Select - Change debug mode to 3 (light editor mode).
  • Triangle - Hold for free camera movement. Use the D-Pad to move, and the shoulder buttons to change angles.
