OSSC vs Uzebox Omega

[danboid]

I got a Mcbazel OSSC 1.7 today. It came with firmware 1.08 but I’ve updated it to v1.12. I was having the same issue I am now with the old firmware.

I’m hoping I’ll be able to get it fully working with my super obscure Uzebox Omega open source 8 bit console that uses RGB SCART.

I think I’ve tested pretty much all of the video output settings and several other options but non of them provide a stable AV signal for video mode 3 games that use
lots of sound or music.

The Uzebox bootloader displays fine via OSSC and so do video mode 74 games (like Flight of a dragon, Output and Stormforce) with sound, work fine, I can run Uzemod to play Amiga mod files fine and I can also run video Mode 3 programs that barely use sound like my Uzebox Stopwatch app fine, its only mode 3 with lots of sound that don’t work
with the OSSC and the Omega eg Donkey Kong, IKD title screen etc.

Most Uzebox games uze mode 3 rather than m74 unfortunately. I’ve tried using RCA audio on the Omega v1.4 which should cut out audio via the SCART but that doesn’t help with the Mode 3 OSSC sync issue.

When I have my Omega connected to my OSSC, the LCD says:

AV1_RGBS 262-p

15.73Khz 60.04Hz

Approx every 5 to 30 seconds, the green LED to the right of the LED panel turns off and the video and audio drop out for a second before the LED comes back on along with the audio and video.

This console works fine with my RGB SCART TVs as well as two other SCART to HDMI converters I’ve tried it with.

I would appreciate any tips anyone might have to try and get more
stable AV when using it with the OSSC.

Thanks v.much for any advice anyone can offer!
