Just be careful with this, OP, and listen to EddieEddie90 and only delete the installed channel titles, not IOS or system or anything else, unless you know exactly what you are doing.Uninstall the wads using YAWMM. That's what I do all the time and it doesn't affect anything. The other way around is with Any Title Deleter MOD, you just go to installed channel titles and you can uninstall any game from there.
