[quote=84800]Good luck. I went with a hardware solution and finally got it working just last night.

Pi b+ with a gert vga666 gpio adapter out to a T-SLG v1.6 scanline generator.

[quote=84803]so the circuitry to switch between them takes up almost all of my GPIO pins

In my humble opinion, you’re asking too much from the Pi.

I’m going with Pi B+ to [u]HDMI to VGA adaper[/u] to [u]T-SLG v1.6 scanline generator[/u] to [u]19 inch CRT[/u] in my arcade cabinet. All my GPIO pins are free.

p.s. – thank you michael! I was about to spend a lot more on a SLG3000 from Germany :)

I picked that HDMI to VGA because it has audio out and separate power in. From what I’ve read, you don’t want to be pulling 5VDC from the Pi’s HDMI port. I’m using [u]a separate 5VDC power supply[/u] just to power the adapter.

I have the HDMI to VGA working, but I just ordered the scanline generator. I’ll have to let you know how that works once it arrives.
