@Juvava not sure how good is that working on 6.1.1, but puae has gotten many improvements in the last couple of months regarding multi-disc support (m3u support among others) so I‘d recommend you to wait a bit and test it again soon.

@unik314r Yeah the problem with that is that I build Recalboxes for friends who enjoy games but no zero about how emulators, roms or much in the way technical. So get them to go and rename and delete files is probably asking a bit much from their technical abilities.
