Daffy Duck: The Marvin Missions (Game Boy)

Daffy Duck: The Marvin Missions takes many cues from the famous "Duck Dodgers" shorts, so much so that it's pretty baffling why they didn't just call the game Duck Dodgers.

Super Game Boy Border
It is possible this Super Game Boy border was going to be used at the last battle, since that is where Marvin's telescope is located. However the default border is used. Game Genie code or Gameshark code  will load this border at startup.



Copyright Screen Collapse
On the Game Boy version, the copyright screen collapses after a few seconds, taking you to the title screen. The Super Game Boy version changes to the title screen instantly.

Title Screen
A background was added to the title screen for the Super Game Boy release.

Level 1, Room 5
Many enemies were removed from the fifth room of the first level, making some of them completely unused in the Super Game Boy version.

Level 2, Room 5
A cannon was removed.

Health Glitch
On the Super Game Boy version, if you move left at full walking speed and then press Right + B on the next frame, Daffy's health will be increased by about 64 units, making the health bar glitch out. This does not work on the Game Boy version.

Select Button
On the Game Boy version, Select can unpause the game and pressing Select + Start during the staff roll resets the game. This does not work on the Super Game Boy version.

Weapon Shot Bugfix
On the Game Boy version, only one breakable tile can be cleared at a time; if you try to shoot many tiles at once, the shots won't be registered. This was fixed in the Super Game Boy version.

Cheat Codes
You gain one point for each enemy or object you kill, displayed as the "score" on the bottom of the screen. On the pause screen, pressing a certain button twice will convert 10 of those points into something useful. These codes do not work in boss battles.

Up, Up gives a laser weapon.

Left, Left gives a weapon whose bullets will bounce on the ground.

Right, Right gives a weapon that will fire automatically when you hold B.

Down, Down gives a weapon that can fire huge balls. This weapon can pass through breakable blocks and can even kill enemies in one hit that are normally immune.

B, B will refill your health.

A, A (Hard Mode only) will refill your jetpack.

Hard Mode
This game has a hard mode which can be accessed by stepping on the cart right at the beginning of the first level. This makes Daffy acquire a lot of speed as long as he doesn't touch the ground. If you manage to reach the end of the room at high speed, instead of loading the next room, the game will show a black screen with the text "Super stage" and you can play through a new set of levels. These levels are almost impossible to be beaten by a human player due to their ridiculous design.

Hard Mode has its exclusive cheat code that will convert 10 points into a refill of your jetpack by pressing A twice on the pause screen.

For this mode you are given 100 points as well as 9 lives instead of only 2, making this mode somewhat more feasible to complete.

Losing all your lives will reset the game instead of bringing up the game-over screen.

Enemies only appearing in Hard Mode


This enemy can't be landed on and has 20 HP. It chases Daffy at very low speed but will dash at him when hit (while puffing itself up). Appears in Levels 2 and 4.



This enemy also chases Daffy, but can be killed in one jump. Appears in Level 2.



This tile appears in a dead-end in Level 2 and will trigger an enemy to drop down behind Daffy when it is shot.
