Solitary Fighter

Solitary Fighter
Developer: Taito Publisher: Taito Platform: Arcade (Taito F2 System) Released internationally: 1991 This game has debugging material. This game has a hidden level select.

Unlike Violence Fight, Solitary Fighter is not a serious contender for Best Video Game Title. It does add a handful of new content, like two new playable characters (the bosses from the first game) and a knife-wielding woman who interrupts fights with indiscriminate stabbing. One of those features was more popular than the other.

SAMMY YOU!

Debug Functions

Round Select

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.

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.

Game Pause

If ROM address 0x00080 is set to a non-zero number, a pause feature is enabled. Put the following code in MAME's solfigtr.xml cheat file:

  <cheat desc="Game Pause">
    <script state="run">
      <action>maincpu.mw@00080=0x0001</action>
    </script>
    <script state="off">
      <action>maincpu.mw@00080=0x0000</action>
    </script>
  </cheat>

Presss Service Coin + 1P Start to toggle a game pause. While the game is paused, press Service Coin + 2P Start to advance the game one frame.

  <cheat desc="Debug Mode">
    <script state="run">
      <action>maincpu.mw@00082=0x0001</action>
    </script>
    <script state="off">
      <action>maincpu.mw@00082=0x0000</action>
    </script>
  </cheat>

By default, this cheat gives all non-CPU players infinite health and freezes the round timer.

Coordinate Display

The game tries to run a coordinate display every frame, but there's a RTS opcode at the start of the subroutine that effectively disables it. Place the following cheat code in solfigtr.xml to enable this feature:

  <cheat desc="Coordinate Display">
    <script state="run">
      <action>maincpu.mw@06BBA=0x4E71</action>
    </script>
    <script state="off">
      <action>maincpu.mw@06BBA=0x4E75</action>
    </script>
  </cheat>

The coordinates of the two players (yellow) and the game's camera and foreground/background layer offsets (white) are displayed on the bottom of the screen.
