Well, first of all, i tested this shinyfying a Pokémon and editing a few IVs and natures and this is amazing, powerful and amazing, i admit it even scares me a bit.
About this
There are people in this forum who is on emunand and, for convenience, have migrated their cartridge saves to .cia, using them on emulated nand wich makes loading the hbl extremely cumbersome. If i knew how to code i would be building a .cia version myself, because it is a need for emunand+digital users.
We all know this, but this question has been asked 15 time at least on this sole thread and an equal amount of time on nearly every thread about homebrews that use hbl's title selector. I'm no homebrew dev, but if I was one I'd have quit by now because of that.
