Twin Eagle (Arcade)

Twin Eagle is a vertical shoot-'em-up about revenge. Read on for more about that mess.

Debug Menu#

There is a debug menu hidden in the game. To access it, place the following code in MAME's twineagl.xml cheat file and turn on the "Debug Menu" cheat after starting a game:

  <cheat desc="Debug Menu">
    <script state="run">
      <action>maincpu.mw@49e6=7b56</action>
    </script>
    <script state="off">
      <action>maincpu.mw@49e6=658c</action>
    </script>
  </cheat>

Use the 2P controls to navigate the menu. Only the sound test appears to be fully functional. The other options do not seem to do anything.

Unused Content#

Graphics#

Seta's logo never appears in-game. Guess making the game wasn't enough to warrant its inclusion.

Story Screens#

There's a button code to view the game's fantastic story, but unfortunately the code doesn't work. You're supposed to hold 2P Button 1 + 2 and 2P Down + Right at the end of the fourth gameplay demo. Unfortunately, the game disables player input during the demo, so holding the buttons won't actually work.

Place the following code in MAME's twineagl.xml cheat file to skip that button check:

  <cheat desc="Fix Story Scene">
    <script state="run">
      <action>maincpu.mw@005EC6=6712</action>
    </script>
    <script state="off">
      <action>maincpu.mw@005EC6=67B4</action>
    </script>
  </cheat>

Developer Credits#

A set of two hidden developer credits, alongside a build date, can be accessed by following these steps:

1. Play the game long enough to get a high score.
2. On the high score entry screen, enter "WLZ" or "MTY".
3. Wait through the gameplay demos until the story starts up.
4. Hold 1P Button 1 + Button 2 before the third story screen pops up.
