Debug Menus

A hidden debug menu can be accessed in this game (and other games using the Nichibutsu Legion hardware) through the following method:

1. Turn the Service Mode dip switch on.
2. Hold 2P Up + Button 1 + Button 2.
3. Keep those buttons held and turn Service Mode off.

This is a simple test of the character graphics ROM.

• 1P Start: Go to next test.
• 1P Left/Right: Change palette number.
• 1P Up/Down: Change graphics ROM offset.

This is a slightly more complicated test of the object graphics ROM.

• 1P Start: Go to next test.
• 1P Left/Right: Change palette number.
• 1P Up/Down: Change graphics ROM offset.
• 2P Left/Right: Alters the "CHG" value, used for palette cycling effects.

This is the menu for a basic stage viewer.

• 1P Start: Go to next test.
• 2P Start: Go to the selected stage.
• 1P Up/Down: Select stage.

This is the actual stage debugger.

• 1P Start: Go back to the stage select menu.
• 2P Start: Speeds up scrolling.
• 1P Left/Right: Scroll horizontally.
• 1P Up: Scroll down.
• 1P Down: Scroll up.

This is a test of every foreground/background block. Unfortunately, the layer and block ID numbers in the top-left don't update properly.

• 1P Start: Go to next test.
• 1P Up: Go to next screen.
• 1P Down: Go to previous screen.
• 1P Button 1: Switch between foreground and background screens.
• 1P Button 2 + Up:: Go forward 8 screens.
• 1P Button 2 + Down: Go back 8 screens.
• 2P Up/Down/Left/Right: Move cursor.

This is just a sprite priority test. Press 1P Start to go back to the character graphics ROM test.
