i made a little video of me playing mario kart 7 and SM3DL with it, if anyone's interested. I also then tried to do ninjhax 1.1b before realizing it doesn't work in emunand at all.
"i wonder if using cfw emunand might work? if there's a way to spoof with 4.5 firm." no I mean ninjhax 1.x doesn't work in emunand regardless, so it has to be done with sysnand
Whats interesting is that forcing 2D with parental controls doesn't fix the stretch problem at all. However, when a game switches to 2D mode (like the CN splash screen), it goes back to normal.
Sure, if you really want/"need" the highest quality there is you can grab remuxes. But will be pretty big file sizes, so disks can be better in that regard.
But piracy is free so...
some bluray rips are kinda crappy, remuxes are a more safe bet, but i usually don't have trouble finding a good rip, there are certain groups to avoid and some to look out for
