OK, this is a pre-merged WBFS file for Wiimms excellent MKW-Fun custom Mario Kart tracks. It combines the standard Mario Kart game and his custom version with loads of new tracks!! Great if the kids (or you!) want a few more tracks to blast around...

I take NO credit for this game, just downloaded and merged/created it for my kids. This was a bit fiddly to do, and thought some people may not be able to do this (or have all the tools to do it), so I figured I would upload this to help them out.
If you like it, maybe buy a new Wii game to keep the franchise going as a thank-you for this freebie! :-)
