Overview

The Shooting Range stage in Wii Play bears the identifier "RPDucScene".

ExcelBin

The scene's common archive contains the following ExcelBin (ver. 1) files:

DucBalloonParam.bin

This file contains parameters for the balloon objects. The file begins with a set of parameters common across all balloons, and is followed by parameters unique to each balloon group.

Lastly, the file contains parameters for the balloon strings.
