I am logged via ssh on osx. I can edit the .lpl files, but after saving them the ROMs are not listed in the appropriate playlist or it will list a word or phrase from the .lpl script.
Script contents: /storage/roms/MAME/digdug.zip Dig Dug /tmp/cores/mame2014_libretro.so Arcade (MAME 2014) 64E58DC3|crc MAME 2014 Arcade Games.lpl /storage/roms/MAME/dkong.zip Donkey Kong /tmp/cores/mame2014_libretro.so Arcade (MAME 2014) 64E58DC3|crc MAME 2014 Arcade Games.lpl /storage/roms/MAME/iceclimb.zip Ice Climber DETECT DETECT MAME 2014 Arcade Games.lpl /storage/roms/MAME/pc_smb.zip Super Mario Bros /tmp/cores/mame2014_libretro.so Arcade (MAME 2014) DETECT MAME 2014 Arcade Games.lpl
Lakka lists Super Mario Bros as /tmp/cores/mame2014_libretro.so If you try to then run it, you get the response “File could not be loaded from playlist”
The rom will run from the load content menu, so I don’t think the rom is the issue.
