I saw an oculus rift vb emulator, and thought, how about a stereogram one?
Can someone create one, the left display on the left and the right display on the right? It would be really simple.
Attached is a conception image.
That would be displayed in the window.

You don't need a new emulator to pull this off. The video settings of Mednafen easily allow for this display mode. You'll want to either make the image very small or sit well back from your monitor, though. The small maximum angular image size limit is the main limitation of the "wall-eyed" stereo viewing method, which is why I prefer the "cross-eyed" method when I free-view (which I rarely do anymore, now that I have a 3D-capable monitor).

As an aside, when I read the thread title, I thought you meant a VB emulator that renders its output as a SIRDS, which would be very difficult if not impossible, since (AFAIK) you can only generate those using a depth map, which is not how the VB stores depth information.

I saw the Google Cardboard and thought wow I must play Virtual Boy on that in 3D. However at the time it was only possible on PC thorugh vbjin with a plugin and medfafen witha .cfg unsupported by mobile

Luckily hunterx was thinking about this coincidently, and has finished it, even with a b/w shader with in my opinion looks better. True 3D

There is still a glitch with the left eye drawing random horizontal lines.

Anyway still waiting on the cardboard I got a lot of the homebrew games from the news section and was glad to see pro yakuu 95' was released for this. I rented and discovered the Virtual Boy it from blockbuster as a kid but usally went for the saturn. I did get it, but it did make me get a N64 late due to parents not wanting to buy another thing. I intend on trying my hand at homebrew I got vbde and some demos

I hate to be the bearer of bad news, but that screen-shot is the same image displayed twice, so it's 2D, not 3D :/

The GUI elements are quite distracting, too (and useless, since one would have to play with a USB or Bluetooth controller, anyway).

I can't wait to see this working correctly (although I still have to build or buy a special cardboard viewer for my giant "phablet" )

It's finished. That actually is 2 seperate images in the 3d parallax, but I had the eye separation all wonky.

I got a bit impatient and printed out the Google cardboard printout on the site. Printed it out but maybe it 3 more inches away from your face, since it doesnt have lenses like your supposed to.

It's awesome!, really feels like the real thing but light and small especially with cardboard and my Galaxy S5

Very nice laying down, however I do recommend taking a break 15mins if you don't have the real cardboard with lenses

Edit: with ps3 controller wired. And you have to go in shader options then menu parameters to set wherever you want it, size, separation

I'll post a how to, you can disable layout too

Attached is the premade .glsl

I forgot mention you have to be rooted and put this shader but it may already auto download it, so you wouldn't even need to do anything


/data/data/com.retroarch/shaders/shaders_glsl/misc/

Other then that it's quite easy

1) Get retroarch in market place

2) Open and go to online updater and get the virtual boy core also update the shaders.Just update everything. It may already have this without doing anything.

3) Then Go to select content

4) Go Select file and detect core

5)Use the / to get into your device storage select your .Vb file

6)Head into shader options in menu (middle touch button with logo)

7)Head down to Shader Passes and knock it up to 1

8)Head down to Shader 0# put to anaglyph to side by side .dlsl file

9) Head up to the top and select apply shader changes

10) Then head back down and select menu shader parameters

11) Adjust the horizontal placement and red toggle. Along with everything else you need to make it perfect for anything that supports this method

It made already have the anaglyph to side by side dlsl auto update when you download the app. So check handheld shades and misc shades for it

Edit: Ah this is important in the menu go to save configuration when your all done!

Also the arrow pointing down on the upper right section disables the on screen layout

Got this working, with no double vision, locked in clear 3d at all times. Sorry but im brainfarting on how to edit but in the shader options/shader menu parameters

set the eye seperation to .60
vertical placement .25
horizontal placemt .77

Works perfect with my Galaxy S5. The image probably could be adjusted even better of an inch to big you have to look around almost

New update on the glsl. Attached

Now has adjustable curvature effect. Good for keeping the screen big but seeing all 4 corners.

Some bugs fixes. It sort of of pain moving these files around on your phone but I think this is the last revision then will be added to the main retroarch. And getting the placement just right is also a chore

I use esfileexplorer to move everything


Also with the b/w filter the whites have a red/blue tint in some areas and in some areas green/yellow in the form of my oled since you basically an inch from your screen with a lense. Kind of adds some nice color
