Help! Screen Resolution changed now screen is black!

[rangefinda]

Hi everyone.

I was messing with the settings of my Gameboy Zero build today and I decided to change the resolution settings. When I changed to a resolution to 480, I rebooted my Gameboy Zero and my screen is now black! It powers on and everything, but no screen activity.

I feel pretty stupid for doing this, is there a way to undo this without having to pull apart my GBZ and re-flashing RetroPie?

Any help is appreciated.

ssh into it with your pc and change the config via a terminal

Thanks!

Or do you have access to the HDMI port?
Or restore the backup of the img file.
