Okay, I'm a bit out-of-the-loop as far as Citra is concerned.
1: Are we able to add custom textures, and higher-resolution textures? I think it would look pretty cool to swap out the textures in Metroid Returns with ones from the Prime games or Other M alongside boosting the internal resolution, and try to turn it into what would pass as a console game.
2: Related question: Is there any way to get shaders working, or would we be using an external program like SweetFX? Using Metroid as my example again, I think the game looks just a smidge too bright, for one thing.
3: Do we still need to decrypt the games ourselves before Citra will play them? I understood it in the beginning as wanting to prevent or slow down piracy, but at this point, all it does is add an extra step.
