Quiz Torimonochou is a quiz game by Taito. "Torimonochou" (捕物帳, literally "capture book" or "catch book") is a kind of detective novel typically set in the Edo period.

Debug Functions

Round Select

QuizTorimonochouStageSelect.png
This game uses the Taito Code:

  • While the game boots up, hold the Service Coin button until the "SERVICE SW ERROR" message pops up on the screen.
  • Then, press 1P Start (×3), Service Coin, 1P Start. The stage select menu should then appear.

Controls

  • 1P Button 1 / 2 / 3 / 4: Adjusts the starting round.
  • 1P Start: Starts the game.

Question Debug

The game will change the way it chooses questions if ROM address 0x00082 is set to a non-zero value. Put the following code in MAME's qtorimon.xml cheat file to enable this feature:

  <cheat desc="Question Debug">
    <script state="run">
      <action>maincpu.mw@000082=0x0001</action>
    </script>
  </cheat>

The game chooses which questions to ask based on a value in RAM address 0x100A1A. Normally, this value is randomly set every time the game needs to load a new question. However, if 0x00082 is set to a non-zero value, the game will instead load questions in number order.

Additionally, if the player starts a game through the round select, the game will go through a special group of questions that's normally only used for the first question at the start of the game.

Game Pause

If ROM address 0x00080 is set to a non-zero number, a pause feature is enabled. Put the following code in qtorimon.xml:

  <cheat desc="Game Pause">
    <script state="run">
      <action>maincpu.mw@000080=0x0001</action>
      <action>maincpu.mw@00025C=0x0007</action>
      <action>maincpu.mw@000264=0x0007</action>
    </script>
    <script state="off">
      <action>maincpu.mw@000080=0x0000</action>
      <action>maincpu.mw@00025C=0x0005</action>
      <action>maincpu.mw@000264=0x0005</action>
    </script>
  </cheat>

Note that the game normally checks for a button that doesn't exist on retail hardware (0x20 for 1P input). This code changes that button to 1P Start.

Region Flag

The region flag at 0x03FFFE is usually only set to a single value, 0x01, since the game was never released outside of Japan. The game has partial support for three other regions; putting the following code in MAME's qtorimon.xml cheat file will allow the user to swap between them:

  <cheat desc="Region Flag">
    <parameter>
      <item value="0x0002">U.S.A.</item>
      <item value="0x0003">World</item>
      <item value="0x0004">Romstar</item>
    </parameter>
    <script state="run">
      <action>maincpu.mw@3FFFE=param</action>
    </script>
    <script state="off">
      <action>maincpu.mw@3FFFE=0x0001</action>
    </script>
  </cheat>

Support for other regions is low: The export warning screen cannot be disabled and always mentions Japan, the game's text will always be in Japanese, and the "Winners Don't Use Drugs" screen needed for North American export is missing. The standard coinage changes for region 0x02 are implemented, but this seems to be part of the standard Taito framework for this period.

What's not standard, however, are the different copyright strings:

Region 02 Region 03 Region 04
© 1990 TAITO AMERICA CORPORATION
      ALL RIGHTS RESERVED
© 1990 TAITO CORPORATION JAPAN
      ALL RIGHTS RESERVED
© 1990 TAITO CORPORATION JAPAN
     LICENSED TO ROMSATR

Yes, Romstar is misspelled as "Romsatr". What they'd be doing importing a game like this is anyone's guess.
