Cyber Tank

Cyber Tank
Developer: Coreland Platform: Arcade (Custom) This game has hidden development-related text. This game has debugging material.

This game was never completed and/or given a public release. As a result of this, keep in mind that the developers might have used or deleted some of the content featured here, had the game actually reached store shelves.

Cyber Tank is a dual-screen on-rails shooter that got poor feedback during the location test phase of development (in August 1988), resulting in the game being shelved and subsequently falling into obscurity.

Luckily, the board from the lone existing arcade cabinet was lent to MAME developers, and the game can now be played by a much wider audience. Game preservation!

Error Handler

This game has a basic exception handler for the standard 68k set of exception vectors. Put the following code in MAME's cybertnk.xml cheat file to trigger an address error in the game demo:

  <cheat desc="Error">
    <script state="on">
      <action>maincpu.mw@0274E=4E4F</action>
    </script>
    <script state="off">
      <action>maincpu.mw@0274E=41F9</action>
    </script>
  </cheat>

Or just screw around in MAME's memory viewer for about five seconds, that should do it.

The game will reset 3 seconds after this message appears.
