@spm2600 Remove the gamelist.xml generated for that system - you can find it in either the rom folder or in \\retropie\configs\all\emulationstation\gamelists\<system>.

The .bin file is not editable in a text editor, the .cue is. Looks like the .cue is valid, check if the filename of the .bin is _exactly Final Fantasy VII [NTSC-U] [Disc1of3] [SCUS-94163].BIN.
Remember that Linux is case sensitive so
Final Fantasy VII [NTSC-U] [Disc1of3] [SCUS-94163].bin is not the same as Final Fantasy VII [NTSC-U] [Disc1of3] [SCUS-94163].BIN.

If it's not a name mismatch, then try posting the whole log file (with verbose logging turned on) on pastebin.com to take a look.

@StigNasty
U can always just take the *.bin *.BIN from the es_systems.cfg

<system> <name>psx</name> <fullname>PlayStation</fullname> <path>/media/usb0/roms/psx</path> <extension>.cue .cbn .img .iso .m3u .mdf .pbp .toc .z .znx .CUE .CBN .IMG .ISO .M3U .MDF .PBP .TOC .Z .ZNX</extension> <command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 _SYS_ psx %ROM%</command> <platform>psx</platform> <theme>psx</theme> </system>

@mitu I have no idea if it's some bizarre edge-case specific to my system, but that's what was broken on my machine and what fixed it - seriously, everything was allcaps CUE and BIN - both the CUE file and the BIN file and the reference to the BIN file embedded within the CUE. All in capitals. I confirmed before renaming that the BIN filename 100% matched the value stored within the FILE "..." BINARY reference in the CUE file.

And I had no music in any of those games.

Changing all the file-extensions to lowercase (including the FILE "..." BINARY reference within the cue file) fixed it.

I would make everything pbp format to save space :D

@quicksilver Yeah, I did the same. Took those that were already converted, the rest I went for bin/cue formats. Converting myself never went right.

Thanks for the guide! I'll give it a try later. So far I'm only interested in PCE-CD and Sega CD games.

I appreciate the help, guys.
