Cannot start mame4all on Retropie 4.6

[ltpitt]

Hi all,

I start mame4all on Retropie 4.6, all I get is this image: https://photos.app.goo.gl/igmjZuminwhJNwE1A

Same identical Raspberry and romset work fine on Retropie 4.5.

Other users have the same problem: https://retropie.org.uk/forum/topic/25847/imame4all-lr-gpsp-don-t-work-on-retropie-4-6 https://retropie.org.uk/forum/topic/27401/mame4all-not-working-in-rpi-zero-image

Can you please help or point me in the right direction for troubleshooting?

Thanks for your time and patience.
