Alright, so I have some neat-looking plastic anaglyph glasses, but nothing looks 3D-ish through Mednafen. I know there’s a bunch of color setups, but I’m pretty sure I should stick to red_blue for my glasses because the other presets look even worse.

Problem is, I still constantly see double. The effect is minimal and I have to be very far from the screen to get any kind of effect.

As a test, I looked at a game only through one eye. What I noticed is that when I look through my left eye, I see reds and reds only, no blue whatsoever. However, when I look through the right eye… I see reds mixed through the blue. Pretty sure that’s what’s going wrong, but I was just wondering how to adjust this so no red is visible at all when looking only through the blue glass?

Tried messing with vb.anaglyph.lcolor but it seems to make zero difference? I’m running the mednafen-0.9.14-wip-win32 build, by the way.

I haven’t been able to see any anaglyph in emulation either, same problem on all tested glasses, one color bleeds through on one side all the time. 🙁

Better get a FlashBoy Plus instead and play on the real thing.

Yeah, I guess so. (Now I STILL gotta get a hold of an actual VB first, though… Sigh.)

I never had any problems w/ anaglyph in RB/RD, though I’ve never tried in Mednafen. I’d try it in RB or RD, just to verify that your glasses can work. You could also open up MS Paint and figure out which colors work correctly with your glasses. Mine are Red/Blue.

Only Mednafen has framerates that go beyond “snail”, unfortunately. But I’ll try tweaking the image and see what red color I’m supposed to be using that way. Thanks for the suggestion.

Alright, setting these:
vb.anaglyph.preset disabled
vb.anaglyph.lcolor 0x8B0000
vb.anaglyph.rcolor 0x0000FF

kind of works. I’m sure I could still tweak the lcolor to get a better effect. Right now it’s between “seeing everything double” and “kind of getting a 3D effect”.

I have found that some red-cyan pictures on the Wikipedia page for anaglyph glasses actually DO work, so even though the blue of my glasses really is blue and not cyan that seems to work better. Maybe. I don’t have any actual red-blue pictures to test with.

I had this problem, but it actually was the glasses. I bought a pair of cheapo plastic frame ones on eBay, but the blue was so thin you could see the whole spectrum through it… To solve the problem, I ended up taking a pair of cardboard glasses that did work, cutting the blue lens out and taping it over the blue lens in my glasses. It’s a pretty kludgey solution, but it works…

Since the goal of anaglyph glasses is to eliminate a given color, to figure out if the problem is with the glasses, fire up any decent color picker and see if there are any shades that appear completely black through the blue side. If you can see color on every hue, then it’s probably the glasses. I’ve heard the purpose of the thin blue is to allow you to see color in the anaglyph, but that doesn’t matter for Virtual Boy, and it just ends up making me see double anyway…

I’ve seen red through the blue glass, so it must be the glasses. Thanks for the heads up, at least I got some backup cardboard ones I can try! 🙂
