That just places the two respective originally seperate monitors into one screen shrinking each image so that both screens fit into one. forgetting about MAME I can't seem to get Gert666 vga in conjunction / Simultaneously with HDMI to have dual screen function working outside of MAME.

Your not going to get an extended desktop out of the box.

fgh:
If a matrox dualhead2go is within your budget it should work (with mame layouts).
It can work without drivers so I suppose it will work on your pi.
VGA version is obsolete and super cheap second hand, but I’m not sure it would work on a pi.
IIRC there is a dvi or hdmi version as well.
itsdanik:
Gert's VGA module's output is analog and the whole thins is passive, so there's no such thing as "what each pin does":
It's simply 18 pins for analog RGB output (6 bits for each color, hence "666"), plus 2 pins for H/V sync, plus ground. That's all there is to it.
Fun Fact: (this info is all available in Gert's github page which is the second result you get when you google "GERT VGA666" - the first being the shop at which it is sold) :cheers:
I doubt you're gonna get two screens simultaneously by simply tweaking MAME options and configuration files without writing or at least editing and recompiling the driver (and also recompile the kernel). Most 'raspberrypi2jamma" boards (there are quite a few out there) are based on VGA666 to drive CRT monitors and Michael Vencio's resolution switching scripts use HDMI timings, so obviously can't have both HDMI and VGA666 out-of-the-box. This is a whole project and $100 is not going to cut it for anyone. If anyone were to build something like this, he would make and sell his own PCBs ;D ;D

Anyone figure this out yet ? :dunno
1x Rpi3B+
1x Gert666
2x Independent Monitors working simultaneously displaying proper respecitve images from PC10 / Punch Out etc
hdmi to vga input (Monitor 1)
gert 666/vga to vga (Monitor 2)
