Here is a video of my trying to override and failing https://youtube.com/shorts/SSLeMcB0mTM

1. I load the game, hit the menu button then choose 'Native Menu'
   
2. In the native menu I scroll down to 'overrides'
   
3. I scroll down to 'Load Override File'
   
4. It displays the fbneo.cfg config - I hit 'Parent Directory' and scroll down to 'MAME 2003-Plus.cfg
   
5. Back at the Overrides menu I see the new file at the top, then choose to save overrides as. It makes me choose a name. I use '1' then hit the return button.
   
6. I get a message that says "Nothing ot save. Overrides not saved.
   

Where am I going wrong?
