Describe the issue

Same as : #357

I'm using the lastest version of the core, and I have the same issue with all my .m3u files (Windows).

If I use a command line with the direct path of the rom, it works fine.

Could you update your RetroArch version and try again? 1.19.1 is old.

https://buildbot.libretro.com/stable/1.22.2/windows/x86_64/RetroArch-Win64-setup.exe

Then provide a log if it doesn't work.

This is my debug version of RA but I have the same issue on my other environment with the latest version.

I found the problem:

Using this command line:
retroarch.exe -L cores\dolphin_libretro.dll "..\Roms\gamecube\Resident Evil Zero.m3u"

This is what I have in my M3U file (which works with other emulators like Flycast or Swanstation):
multidiscs\Resident Evil Zero\Resident Evil Zero (Disc 1).rvz
multidiscs\Resident Evil Zero\Resident Evil Zero (Disc 2).rvz

[libretro INFO] 36:31:113 DolphinLibretro/Boot.cpp:103 I[COMMON]: Suppressed popup: Warning - Files specified in the M3U file "..\Roms\gamecube\Resident Evil Zero.m3u" were not found:

[libretro ERROR] 36:31:120 DolphinLibretro/Boot.cpp:406 E[BOOT]: Could not boot ..\Roms\gamecube\Resident Evil Zero.m3u. M3U contains no paths

And if I use this, it's OK:
..\Roms\gamecube\multidiscs\Resident Evil Zero\Resident Evil Zero (Disc 1).rvz
..\Roms\gamecube\multidiscs\Resident Evil Zero\Resident Evil Zero (Disc 2).rvz

Cwd path is being set to the core directory, not the "rom" (m3u) directory in that code path. Might be a common problem in various cores or a inconsistent core specific mélange of problems

Needs to be fixed but to tell the truth I've used portable playlists with relative m3u ROMs in a SAF path as base directory before which is a small miracle it works (saf path m3u and relative paths inside figuring out the parent path and creating a valid saf path) so this might be specific to the CMD line and the graphical UI always sets the cwd to the rom dir before feeding the core the rom.

You can try to set absolute path inside the m3u. That might or might not work with portable playlists (for NAS saf paths). If you're using that feature.

I never tried but I suspect it won't work (because the portable playlists mechanism is setup to replace a path prefix in playlists, not in absolute files treated opaquely as roms). Then again maybe it works jdgleaver did good work with that feature and maybe he predicted the problem with absolute cues and m3us.

Anyway you did nothing wrong and I always prefer and recommend relative cues/m3u paths exactly because of relocation problems and using saf paths, so this really should be fixed and checked if it doesn't occur in more cores.
