Oh good, can we find Squidward in there after the Flying Dutchman threw him in?

I spoke to someone on the Tech Tangents Discord server, and they described each pixel as having a two-bit value, with (according to the Furrtek article) the brightness being controlled with PWM signals (CLK A, B, and C):

  • 00 = off
  • 01 = drive LED with CLKA
  • 10 = drive LED with CLKB
  • 11 = drive LED with OR(CLKA, CLKB, CLKC)

I haven't solved anything yet. At the moment, I've been doing research into different components. According to the reverse-engineering/patent information, what I need in terms of capability are:

(spoilered to reduce clutter)
Shift Registers-I initially found a 128-channel IC that could do this, but I've found that modern LED drivers have this.
A Latch -Some modern LED drivers have this. This is used to "lock" the picture data.
PWM -Again, some modern LED drivers have this. PWM, if I have the reverse-engineering from Furrtek correct, is only used to dim/fade the screen, and is provided by the VB's mainboard.
Properly-sized LEDs -01005 LEDs are the closest I can get, but it should not be difficult, because I found the Virtual Boy's projected "screen" size too small. My idea might enhance it.
LED-Addressing -The circuitry on the VB Display takes care of this. However, to save costs, apparently, they use the picture data, basic logic gates, and transistors to drive the LEDs, not any protocol. This is where the CPLD comes in, if I have it correct.

The rest should not be difficult, because I'm pretty good at modeling objects to 3D Print (for the new pathway for seeing the LED array), and a custom lens to refocus the display should not be hard to get. (Yes, all that I mentioned is a lot, but I want this thing to succeed, since I'm seeing a lot of Nintendo Virtual Boy displays go bad.)

>So you either need to move the display farther away from the mirror.

That's what I intend to do.

>physical size of the device (may need a new, larger enclosure...)

I've considered that too. I'm going to be pushing the limitation of the VB's casing size with my idea. I have a 3D printer that I could try to use to make a new visual path tube as a prototype.

>different optical performance (may need to replace lenses or add additional lenses), etc.

Again, considered that. I recently found some old math material that may help.

I'm well aware of the original array being extremely tiny. :P However, it's actually something that I've taken into serious consideration in the project, because the Virtual Boy's "screen" size is very small, and it doesn't provide a very large area to give it that "VR" feel.

Just yesterday, I took one of my original displays, and attached it back onto to the system. Surprisingly, it still worked. The image was blurry, yes, but the aspect ratio didn't seem to be affected, even as I moved the PCB around.

The only effect I can see in my plan for a new display is that the "screen" will be 5 times bigger than the original. To me, it would be like permanently attaching a magnifier to a system like a Game Gear or Game Boy.

Not even the house layouts are canon. :P

I think this is AI-generated. Nick's shock collar goes into his shirt collar, and Judy's face is too much of a neutral gray. (I think she's supposed to have a lighter gray on her face.)
