This is a mod of Pokemon Rumble (Wii) that was made for the shiny hunting community event Rumble Weekend! The original Pokemon Rumble contains only the 1st and 4th gen Pokemon, but this mod reintroduces the 2nd & 3rd gen Pokemon (and their shinies) to the game in a new terminal known as "GX"! The layer of fog on all stages has also been removed, and the collection screen has been updated to support all 493 available Pokemon!
The original base game also remains fully intact in order to preserve the rarity of certain Pokemon.
Included are 3 bps patches to be applied to a USA version of Pokemon Rumble to get you into GX! Due to slight differences in dumps of the games out there, there were 3 patches made to ensure it works. (details on how to obtain the original game obviously not provided)
This is fully cross-compatible with save files from the original Pokemon Rumble (USA version), and it can be installed on actual hardware via homebrew. This patch currently ONLY works with the USA version of the game due to slight scripting/file structure differences that exist in the JP/PAL versions of the game, so if you want to play it on a Japanese or PAL Wii, make the resultant .wad region free after patching with a tool such as ShowMiiWads.

This mod is still very much a work-in-progress, and for full details on what's available/what is planned for the future, read the readme file inside the zip folder!
