A kind Youtuber informed me the old link had died, so here's another one.
This file includes the movement editor, some of my finished levels and other miscellaneous stuff that may or may not be useful to you.
Transfering the MegaFile to your Wii:
First off, if you already have a Blast Works save file and you want to keep anything therein, BACK IT UP FIRST. Copy your save onto an SD card from your Wii, access it via your PC, then find data.bin in the directory "/private/wii/RBRE/" and set it aside somewhere outside of the Wii-specific directory structure, being sure to properly identify it should you want or need to access it again.
- If you don't already have Wii data on your SD card, unzip the entire menu tree to it's root directory. Otherwise, simply copy the game-specific folder RBRE into the Title folder.
- It should now be visible as save data on your Wii, copy it to your system from there and you're good to go!
And don't forget....BLAST WORKS FOREVER! :)
