Mset.. works, but it's a sloppy as hell entrypoint that blanks every time you run dsiware or launch a ds cart, and even if you don't run these it can still blank seemingly randomly.Lol, I think that got lost in the busy thread. Sounds perfect. I'll go read about how to do this
I'd suggest still using CtrBootManager with themehax as it's a much cleaner and more powerful way to control your setup, but whatever works best for you.
