How to Mix Weapons in RE4 Wii Edition

Plug your GameCube controller into controller Port 1 on the front of the Wii.

Insert the "Action Replay" disc into the Wii's disc drive and turn on the console.

Scroll through the list of games that appears once the Action Replay program finishes loading. Locate "Resident Evil 4" on the list and click the "A" button to load the cheats.

Push the eject button on the Wii and substitute the "Resident Evil 4" Wii edition disc for the "Action Replay" disc.

Wait for the game to load. Use the main menu to load a game with a character that has a special weapon such as a rocket launcher.

Press the "Y" button to open the start screen.

Use the left thumbstick to select a weapon designed for the chosen character. For example, select the Punisher if playing with the character Ada. Highlight the chosen weapon and press the "A" button.

Use the left thumbstick to highlight "Exit" in the upper right corner and press the "A" button.

Press the "Y" button to open the weapon select screen again.

Highlight an egg or a grenade and press the "A" button to equip the chosen item.

Highlight a weapon your character is not designed to use. In Ada's case, you may select a weapon like the rocket launcher. Click the "A" button to mix the chosen weapon with the originally selected weapon. The image of your character in the right pane of the screen will stand with both arms fully extended if the process was successful.

Highlight the "Exit" option and click "A" to return to the game. The mix of the weapons causes the originally selected weapon to fire ammunition with the same potency and rate of fire as the weapon you chose to mix it with. In this case, the Punisher would fire rounds as powerful as rockets.
