Debug Functions

Level Select

The Taito Code is here again!

To access this stage select, hold the Service Coin button while the game boots until the "SERVICE SW ERROR" message pops up on the screen. Then, press 1P Start (×3), Service Coin, 1P Start. Start a new game to access the stage select.

Char Check

Put the following code in MAME's nightstrm.xml cheat file to replace the standard test mode with this Character Check:

  <cheat desc="Change Test Mode to Char Check">
    <script state="run">
      <action>maincpu.mw@00A464=850C</action>
    </script>
    <script state="off">
      <action>maincpu.mw@00A464=4C3C</action>
    </script>
  </cheat>

• Press Left / Right to cycle through character blocks.
• Press Up / Down to change the current zoom level (7F is the maximum).
• Press Button 1 / Button 2 to change the current palette.
• Pressing 1P Start should access "TEST MODE2", but the function no longer exists so the game resets instead.

Error Handler Leftovers

Most of the standard 68000 exception vectors have entries in the exception vector table, but they all point to ROM space 0xF00000. That ROM space might have been used by development hardware while the game was still being tested, but it's empty in the final game.

Unused Graphics

Used	Unused

An alternate version of the casino sign, probably meant to be used when the game is set to a non-Japanese region. The yen version is used regardless of the set region.
