WarioWare, Inc.: Mega Microgame$! is the first entry in the WarioWare series, released for the Game Boy Advance in 2003. The objective of the game is to complete microgames within a time limit, scoring a point for each that you complete. The microgames are varied in gameplay and are sorted by their general theme using a cast of original characters, including Wario from the Super Mario franchise.
9-Volt's stage is themed around Nintendo's history. One the microgames in this stage is based on Balloon Fight, specifically the Balloon Trip mode of the NES game. In the microgame, you must avoid falling into the water or touching the Sparks as the screen scrolls. The Balloon Fish will also grab the player if they stay close to the water for too long. Once the microgame has been seen in 9-Volt's stage, it becomes unlocked in the grid, where the player can choose to play it at any time. In order to "clear" this microgame, the player must score 20 points. While it is highlighted in the grid, a brief description will scroll past on the bottom of the screen:
"[Balloon Fight] CLEAR 20 Pts. Fly through the air, but don't run into the little sparkling fires! Simple! But Challenging!"
The microgame's controls are left and right on the d-pad to move, and the A button to rise. The release date is listed as "1986: NES."
