Before I was able to get a Virtual Boy in an anaglyph mix using 2 Virtual taps and a 90s video mixer.
I was looking for a way to do that without heavy equipment to make it less of a hassle to set up an doesn't need heavy gear
You can do it with passive VGA cables. This is what you need for it to work:
A couple VGA male to male cables.
If you don't want to damage your VGA port 3 of these, or if you don't care as much, 1 2 VGA Female to 1 VGA y cable.
A VGA female to VGA male dongle.
And a little time soldering on the VB
Open a VGA double tapped virtual boy, operating on the right eye by taking out the clock ossilator, then bridge the connection where the clock ossilator was to the main clock. And connect the ground to the ground corner of the timing chp.
Yank pin 13 and pin 14 on the VGA F->M dongle.
place that pin yanked 13 and 14 VGA dongle, and plug it into the right hand eye VGA path
Y the 2 VGA cables into one,
And unplug and replug the combined video cord while the power is on to the TV you're playing on.
Press right eye's color change button to have the right eye as cyan.
Wear MONOCHROME OPTIMIZED red and Cyan Glasses, or possibly "modern Dubois glasses" if viewing on an HDMI monitor.
Enjoy the Virtual Boy in red and cyan without feeling like a peeping Tom, on stream for all to see. Do what Nintendon't... Share Virtual Boy on Video streaming.
By the way, trying to enjoy a VB on CRT is not adequate because he way TVs blend the places to between pixels in in-between colors, you're going to get color bleed by having these yellows, in betweens the reds and cyans,
It's better on an HDMI monitor because it doesn't blend reds and cyans off the axis, each pixel is either red, cyan, white, black, or a shade along that axis,
By the way, I'm selling my Video mixer on eBay with "Anaglyph settings" as default. It's an Analog Way Pulse PLS 300
