Darkwing Duck is an action game for the Nintendo Entertainment System. It is based on the 1990s animated series of the same name.

This hack adds a simple but complete sound test mode to the game's title screen. There's a new sound test display at the top of the title screen, and the main theme plays automatically there, whereas in the original game the title screen remained silent.

Patch version 2 fixes some things:
- Darkwing Duck's shadow on the title screen no longer misaligned with the main character.
- Songs and sfx are now counted in decimal instead of hex (so now they go from 00 - 63). This is more natural.
- Fixed portrait graphics on the map screen.
