@davidgrohl As far as I know, the current version should be compatible with 1.7.6, it's not a breakning change. However, as @dankcushions said, if your installation is too old and it's based on a previous Raspbian release, your best option is to install a new version. As always, backup your installation before making major changes/upgrades.

Done it! I succeeded to enable blargg's filters, thanks so much.

I should have looked harder. I found the clarification I needed. Those options are saved by design:

@BoogieMan core options are managed from RGUI (select+x) -> quick menu -> options
They are saved automatically.
See documentation for more info on using retroarch.
