Hi all I am using a Pi 400 and have the Damso Nostalgia Trip V3 Ultra, the intro is spectacular but unfortunately after the intro I get the blue screen message

“if this is the first boot of Retropie – make sure you are using the correct image for your system.

Check your rom file/folder permissions and if running on a Raspberry Pi make sure your gpu_split is set high enough and or switch back to using carbon theme”

Is theDamso Nostalgia Trip V3 Ultra build compatible with the Pi400 ? 

Has anyone resolved it ? Ive looked in my raspi config there is performance options section and my gpu memory is set to 512, had a brief look around for the same error message but only found 1 but no reply.
