For those interested I find it a lot easier to just use my IPad to add roms as well as emulators. I use FTPManager app from iOS to add roms and an app called Terminus to add emulators.
heya !
nice tip ! maybe if you have time make a visual tutorial would be great 
I will try to put something together this week. But it’s basically everything you do that’s been mentioned in the board for adding emulators and roms just using an iPad.
I use Documents by Readdle.
