Put Super Toad 67 in the world folder and the LunaDll and smbx 22.214.171.124 file in your SMBX folder.
This smbx 126.96.36.199.exe file isn't the same as the original smbx 188.8.131.52 file, so you either replace the old file or rename this new file (or keep this file if it already has a different name).
-- edit --
Dropbox, Mediafire and Google Drive keep deleting the files.
Does somebody know another good file hosting site?
