Where is this Mame Config Line Hiding?

[AlphaBetaPie]

I recently found the options in the Mame Retroarch core to disable the copyright and emulation warnings that sometime pop up (IE: telling me the graphic driver is bad and there are known emulation issues every time I load up games like Galaga for example). But I want to include this in a custom config file with some other settings I use, and not set it in the menu. I don't want all the other lines it creates when you "save core options." I tried searching the config file it generates from Retroarch to see if I could locate the line, but it's evading me. It must be named something weird, as I was searching for something like "show_copyright_warning=false" but nothing like this is present. I even used WinMerge to try and compare the files, but couldn't find it.

Any help on that?

@alphabetapie those are core options:

/opt/retropie/configs/all/retroarch-core-options.cfg

mame2003_skip_disclaimer = "true|false"
mame2003_skip_warnings = "true|false"

Edit: https://retropie.org.uk/docs/RetroArch-Core-Options/#setting-core-options-per-rom

Setting Core Options per-ROM

You may prefer to apply Core Options to a specific ROM, and not for all ROMs within that core. To do so, follow the above instructions, but instead of exiting the RGUI at the end, select Create game-options file at the top of the Options menu. This will create a Core Options .opt file specifically for that ROM within:

/opt/retropie/configs/all/retroarch/config/core
(where core is the name of the Core)

The file will be ROMname.opt. To remove the configuration, delete the file.

@alphabetapie as always, the docs explain this:
https://retropie.org.uk/docs/lr-mame2003/#nag-screen
https://retropie.org.uk/docs/lr-mame2003/#skip-warnings-screen

you'll note both point to the core options doc which show where the per-rom core options files are stored. it is not the same file as retroarch configs/overrides.
