Lakka + Pi 4 + RetroTink Ultimate + RGB CRT

Will be trying this soon. Anyone else interested to get all these things working together?

Well well well, it works :slight_smile:

The main change I had to make was that a width of 1920 was too narrow. 3520 worked on my CRT (a 32 inch Sony Wega). I suppose the key thing is to use 240 as the height.

The other thing I noticed is that once you add the config.txt lines to boot to CRT, you have to remove (or comment them out) to move back to HDMI. I expected this and it works just fine.

Speaking of the width and height mentioned above, that’s the second change… you have to turn off custom aspect ratio and set it back to core provided.

So that’s one edit to config.txt and one in-menu change, and I can flip between HDMI and CRT. Pretty easy. Would be nice if you could just hot swap them, as it were, but I’m very happy to have gotten to this point.

Actually it seems that on the fly it should be swapped between 1920 for the narrow Mame games, and 3520 for everything else / consoles. Not sure if there’s a way to pre-set this, but it’s a pretty quick and easy tweak should I want to play a Mame ROM.

eyyy, glad you got it going! Got any pics??
