Also known as: Wonder Boy III: Monster Lair (JP)
Two different debug screens are accessible in the game:
For the first screen, pictured above, at the title screen, hold I + II and press Run. This screen contains a sound test and a controller input test.
For the second screen, get a high score (minimum 30,000 points), then enter HU7 as a name (press and hold Select to access the numbers). At the title screen, press and hold I, press and hold II, release I, and press Run. The screen above, which contains 8 switches and a round select, will appear.
|This needs some investigation.|
Discuss ideas and findings on the talk page.
Specifically: Figure out what each switch does.
