Debug Functions

Round Select

This game uses the Taito Code: While the game boots up, hold the Service Coin button until a "SERVICE SWITCH ERROR" message pops up on the screen, then press 1P Start (×3), Service Coin, 1P Start.

Use 1P Up / Down to move between options, and press 1P Start to select that option. "Test Mode" is the game's standard test menu, and "Reset" does exactly what it says.

Style Check

There's a frame / hitbox viewer hidden in the game. Put the following code in MAME's viofight.xml (World), viofightu.xml (US), or viofightj.xml (Japan) cheat file. Then, hold the Service Coin button while starting a new game to access this menu.

  <cheat desc="Enable Style Check">
    <script state="run">
      <action>maincpu.mw@002388=6614</action>
    </script>
    <script state="off">
      <action>maincpu.mw@002388=6014</action>
    </script>
  </cheat>

(The Service Coin method is coded in the game, but the game effectively ignores the input by using a BRA opcode to always branch into normal gameplay. This code just changes it back to a BNE opcode.)

Controls:

• 1P Left / Right: Change frame offset by 1.
• 1P Up / Down: Change frame offset by 10.
• 2P Start: Flip frame horizontally.
• Service Coin: Toggles Area (Dark blue) and Attack (Light blue) visibility for the current frame.
