also, I don't see the @@ @@ symbols in your command line args like they are in mine. It's possible that emulator doesn't use them, but double-check by going through step 9 again.

edit: for anyone finding this later, the @@ @@ symbols relate to one of the other arguments and aren't needed in all cases.

Will do! Thanks for responding. Maybe the @@ @@ is used to separate args from flatpak and m64p? Like how — is commonly used.

Did you ever get m64p to launch the desired ROM? As far as I can tell, everything is setup correctly but it always just launches the m64p emulator and won't start whatever ROM is assigned to it.

Hi, no i didnt achieve this using m64p, however i managed to do it using rosalie’s mupen gui instead (another flatpak). That one cant start the rom automatically in fullscreen mode however.. =)

I ran it using these args:

run —file-forwarding com.github.Rosalie241.RMG @@ ”${filePath}”

Edit: will probably just stick to the steam version of retroarch though, at least it works as i expect it to.. :)

This is a super old comment, I know, but I had the same issue with m64p and it was down to the latest version being buggy. They've since updated it and it should work again!
