@udb23 I only put this thread here because I saw several people on here and Github saying that Artwork and Samples for lr-mame2010 didn't work. I'm not going to attempt to make configs manually for all the Vertical games, that's why I asked if it could be batch made in my first post :) and lr-mame2010 already makes it's own per game config files with custom controls etc. so these will be overwritten/ignored. I decided to use Android for MAME now (mame4droid 139) as it's far superior. Cheers.

I'm working to change the video settings in retroarch to best fit to the bezelproject artwork. I have about 400 games in MAME 2010 and had them all working fine then something happened and now, like others, I get the "Failed saving config to "/opt/retropie/configs/mame-libretro/retroarch.cfg" error message.

I've tried deleting the retroarch.cfg file
I've checked permissions and they're pi:pi

I've tried the suggestions listed here and it seems like most of the suggestions here, and over at the retroarch discord are just "try this and cross your fingers."

Surely someone knows what's going on and how to fix it.

@mediamogul When I change the controls in Sony_Computer_Entertainment_Wireless_Controller.cfg it changes the controls in games, but doesn't change the controls for the menu so I think that is good.

@WhyCan'tIJustDie

Thanks, I am new to these forums, if I can can how would I mark this a solved

I think if you asked the questions with unresolved then you can mark as resolved. I'm actually not sure how it works lol

@gizmo98 That did the trick. Thanks!

@rsimmy it should be permanent. Have you moved the configs into another device anything? Or any custom scripts? Did you install RetroPie under a normal user instead of root?
