Enable the Game Genie codes SANT-A4YE and AVHA-AAEN, then input the level select code above. Now, instead of the regular level select, this simpler version will appear.

This screen uses a rendition of "Hooray for Hollywood", which is inaccessible from the sound test. It is said this tune might have been cut due to licensing issues.

Unused region lockout screen

Daffy Duck in Hollywood is not region locked, however code exists to stop the game running on a non-PAL Mega Drive. Use the Game Genie code RE5T-E6W6 to re-enable the feature.

Unused head hitting mechanic

In the final game, nothing of consequence happens if Daffy hits his head on a ceiling; he just falls down. However, code exists within the game that instead causes a momentary pause accompanied by an animation. Hit your head three times in this way without moving left or right, and Daffy's head will grow a lump.

It can be re-enabled with the Game Genie codes RE8T-C6VL and RE8T-C6VN.
