Mega Man: The Wily Wars is an action platformer game for the Sega Genesis. The game is a collection of the first three Mega Man NES titles, with an addition of new content exclusive for the Sega Genesis. In Japan, the game was originally released under the title Rockman: Mega World.

Wily Wars: Weapon Master is a hack for Mega Man: The Wily Wars that replaces the redundant functionality of the "window" button (A by default) with the ability to switch between any weapon in the game, regardless of progression or game mode. This means you can take weapons out of their native games and play through Mega Man 2 with weapons from Mega Man 1 and 3, for instance.

To use this feature, hold the window button and use Up and Down on the D-Pad to change your current weapon. The game is paused during this to make choosing between so many weapons easier in crucial moments.

By itself this hack does not have other improvements such as region unlock, buster speed etc. but it can be applied on top of such patches without issue.

Notes:

-The weapon switch works even if your bullets are still on-screen. The only exception is Time Stopper which can't be switched if in use.

-To prevent crashes, you will be limited to only MM1 weapons during the Copy Robot fight in MM1 Wily Stage 2.
