Edit in the terminal

[stevep]

Ok I'm in the terminal and I have the es_systems.cfg up. What commands do I use to edit and save. I typed in the command
sudo nano /etc/emulationstation/es_systems.cfg I want to add .ecm extentions for the pcx emu.

Obviously .ecm isn't listed as a viable extension for PSX, but if you're sure that it will open, give it a go and be sure to report back with your results. If it works, this might need to be added by default for all users to take advantage of.

To begin, you shouldn't edit that file directly. Make a copy to the alternative directory with:

cp /etc/emulationstation/es_systems.cfg /opt/retropie/configs/all/emulationstation/

Then you can edit it with:

nano /opt/retropie/configs/all/emulationstation/es_systems.cfg

From there, the systems are listed alphabetically, so work your way down to 'psx' and change:

<extension>.cue .cbn .img .iso .m3u .mdf .pbp .toc .z .znx .CUE .CBN .IMG .ISO .M3U .MDF .PBP .TOC .Z .ZNX</extension>

to:

<extension>.cue .cbn .ecm .img .iso .m3u .mdf .pbp .toc .z .znx .CUE .CBN .ECM .IMG .ISO .M3U .MDF .PBP .TOC .Z .ZNX</extension>

After you've made your edits, press 'ctrl+o' to save and 'enter' to confirm.
