Wow it looks great. 3DS is becoming emulated, check out Citra. It's starting to play some commercial games, albeit very slowly.
PS3 is also being worked on, on one project, they can play homebrew, but no commercial games yet.
I'm sick to the stomach about r/emulation. The no roms rules are just stupid. Where do you think everyone gets their roms?
This is a start.

You could add it to the settings list. I added quick options to switch between HDMI audio and 3.5mm Jack.
