It seems there’s a hoax regarding this game having a secret sound test. Couldn’t get the code to work at all. Investigating the ROM I could not find any information about it having a sound test mode. So I created one. At the title screen, press left / right to use it.
Patching Instructions:
1- Download Darkwing Duck NES Sound Test
2- Get your Darkwing Duck USA ROM (please legally own the game). Make a BACKUP of it!
4- Open lunar ips, click “Apply IPS Patch”. Locate the ips file contained in the zip.
5- Locate the Darkwing Duck ROM to apply the patch to.
Done! Now play it on your NES emulator of preference!
