@Melvin.FoX exactly as @herb_fargus said. you asked about the possibility - what other answer is other than what i gave? it's possible. it's open source. that experimental core is so barren of basic features that it can't see why anyone would work on it, like i said previously. we do get a lot of people asking for this feature and that feature - my to do list is long enough with just the things i want!
just because i'm a moderator doesn't mean i represent the retropie project. i just delete the occasional spam post because i'm always on here :)
