I installed 22.31 V4 NESRGB. Wasn't sure if anyone else has experienced this. I'm not sure where to troubleshoot. I tried installing the NESRGB with the voultar's expansion audio and voultar NESRGB QSB kit. On the NESRGB board, the LED 1 stays on. None of the other LEDs light up.
On boot up, I would get this glitched screen with an everdrive n8 pro. I'm using HD retrovision cables with a retrotink 5x. I tried loading a game on the everdrive and there's no audio as well.
Pictures of the installation:
Apologies. I was able to get the images to work but some reason it's blowing up huge for me.
