@boston BC, that looks like superb work. I think I've used it before, there was a pegi - based categories ini somewhere that I ended up using, i initially tried combining data from each ini, failed and gave up! Could you drop me a link, i mioght well give it another go!
You've brought up some interesting points. Perhaps we could have an agreed couple of designated user custom categories and standardise the rest. Does the data from GameTDB have a finite number of categories? I was thinking there's a LOT of stuff available in WiiBackupManager that isn't in wiiflow, but they both work off the same data set. right? You seem to know a lot more about what you're talking about. Fancy starting a categories ini implementation thread?
My first post would be "Does editing categories have to be done with a text editor when I've got over 300 titles to edit, each with 21 variables?", followed by " why can't we have, eg comma separated values or summat, or whack the whole thing in a open excel - type format. or would that make it wayyy too complex for wiiflow?"
BTW you hit the nail on the head - the idea is to allow the user to block whole categories, and potentially whole plugins homebrew etc, by nominating them for lockage, dare i say locktitude, lockliness and lockidity in the relevant ini.
