I figured out the issues, but apparently it is JUST a launcher, when I exit via alt+f4 the dolphin gui shows up and asks for verification, then retro arch appears, so it's actually worse as far as going keyboard free. Oh well, was worth a shot :)
If you want the dolphin emulator, install steam on your pc. Steam link on your pi. Add the dolphin emulator to steam. You can stream dolphin emulator from your pc via steam link to a raspberry pi. Steam link is in the expirimental section.
i have a project in mind that i have always wanted to do. My favorite child hood game was the GameCube's Luigi's mansion. In this game, you get what is call the GAME BOY HORROR. i want to remake this game boy horror and as one of the features, be able to play Luigi's mansion on it. i have the ROM for it and dolphin, but thats about it.
