RetroArch command line loading options files?

[crusadeRGP]

Is there a way to load a specific core.opt options file using command line the same a core.cfg -c?

AFAIK, there is no straight up command line argument to load .opt files but you could use the --appendconfig <PATH_TO_ADDITIONAL_CUSTOM_CONFIG> cmd argument with the core_options_path = “PATH_TO_CUSTOM_OPTIONS” as a line inside the ADDITIONAL_CUSTOM_CONFIG.cfg to override the options file, see -here-

It is still loading the Genesis Plus GX.opt file after I followed the steps you provided above?

I have two configuration setups in LaunchBox for RetroArch cores with one being the standard (Retroarch.cfg) another for bezels (Sega Genesis TV.cfg)

Check your command-line argument, with the --appendconfig you are pointing to the 'Sega Genesis TV.opt' you suppose to point it to straight to the 'Sega Genesis TV.cfg.' Remember 'Sega Genesis TV.cfg' is an 'appended' configuration so every line in there is replacing the equivalent line in the standard Retroarch.cfg but everything else is staying the same, that said you might not need the -c "config..." part at all if you use it only with these three changes/lines. 

This is how I use the --appendconfig function myself:

 

This way I can use the standard Retroach.cfg along side the For_LaunchBox.cfg to change some settings only when using it via LaunchBox.

Edit:
In the standard retroarch.cfg file this specific line looks like this by default (core_options_path = "") so that RetroArch can use the auto-override set by Core/Folder/Game_Name.
By appending yours [--appendconfig "...Sega Genesis TV.cfg"] this line (in red) is "replaced" temporarily by the new one core_options_path = ":\...\Sega Genesis TV.opt".

Long story short you are just appending the Sega Genesis TV.cfg for the changes so that the .cfg points to the specified .opt file.

Hope that this helps a bit more... 🙂
