Create Game Options File vs Save Game Overrides?

This might be a stupid question but can anyone explain what the difference is between Create Game Options File and Save Game Overrides?

Create Game options file saves the core options for the selected game. Think of it like saving the emulator settings since the cores are basically the emulators and each one has it’s own unique options that have nothing to do with RetroArch itself.

Save Game overrides saves the frontend/RetroArch settings for the selected game. Theses are all the options for RetroArch itself, outside of individual core/emulator options.
