@meleu Yes. That's what I was saying :-)

@ProxyCell It's a useful feature to be sure. Since RetroPie is built on Raspbian and can also be installed on Ubuntu, there are all sorts of underlying functions of linux, we could really have a wiki on retropie, retroarch, and linux... any suggestions on the best way to lay it all out?

@vbs It's not a bad idea (I have thought a lot about it - especially when I was doing the reorganisation of the retropie-setup menus), I just think it's really only retroarch which would benefit (maybe a couple of others) - so it's whether the work is worth it. I'm pretty certain it will be me who has to maintain this long term too. I'll see how retroarch develops though and reconsider it in the future if it seems required.

would it be relationed with __persistent_repos of the 4831258dbaf6d8af93abff513cb7c10b972df488 commit?

It would be easier to update your romset.

@TonyTheTGR
Probably yes, it's described in the Wiki:
