I avoided having to work with these this time because I just found a usable .WAD file that did what I needed but for the future (or even just for my self-edification), how do these files work? Apparently the "tmd.1" file needs to be renamed "title.tmd" and the numbered files with no extensions need to have ".app" appended as an extension but after that what next? Is there an application that can compress these files into a single .WAD for installation on a Wii?
