Alternatives to using the official Master System 3-D Glasses

This thread was inspired by the ongoing discussion on the Maze Hunter 3-D review, in particular the following statements:

Apparently other glasses can be used as well, but there may be issues. This AtariAge-Thread for instance says that you can use those Asus PC 3-D shutter glasses, but they caus issues with some games. The Famicom 3-D system is apparently fully compatible.

So that got me curious:
- Are there modern alternatives that can be used instead of the original Master System Glasses (aside from the Famicon glasses I mean)?
- What would you need to use these glasses on a Master System?
- (If there are certain issues with some games): Where do potential issues come in, how do you address them, and what would you need to look out for if you wanted to look for alternativs and prevend these issues (like for instance a doubled picture)?

Still no replies? Does nobody have any experience with this?

There are not really a lot of "modern" shutter glasses being made so it's a hard question to answer. I have the LaserActive goggles and have use them before (they are the exact same tech) and are about as comfortable as the Famicom ones.

The tech in these is super simple, you just need something that can open/close the shutters in sync with the video.

What if you just blink your eyes really quickly?

I have the ASUS glasses myself. They're the closest I've gotten to perform like the original. However, they're not always cheap.

So how do you accomplish that? Do you need to hook the glasses up to the Master System in some way? Or do you need to find glasses that have the exact same open/shut-timing the Master System Glasses have? Sorry if these questions are a bit naive, I don't have much experience with shutter technology.

Well, I guess if you can blink with each eye independently, one after another, in the exact same timing the corresponding images flutter across the screen, you just might achieve that same effect. Good luck with that. :D

I've heard that the ASUS glasses are slightly off with some games though, is that true? And if so, what causes the issue - is it because of a different shutter timing/frequency (if that's the correct term)? Is there any way to find out about that, any datasheet or something, that might contain that information?

Ahh okay, from my understanding in general the 3D shutter glasses are a two part system normally:

1) The adapter which syncs the open/close signal with the video
2) The glasses which open and close the left or right eye shutter rapidly to create the 3D effect in sync with the video shown on the TV

The SMS 3D adapter (and the Famicom, and the laseractive) has a spot in it where you plug in a phono jack, which is similar to the one used with headphones.

The glasses are transparent pieces of plastics with little shutters that open/close in front of them, with a cord coming out that terminates in a phono plug that goes into the adapter.

The adapter takes a video signal, and then processes it and sends out commands to the plug that say OPEN Left & CLOSE Right, then OPEN Right & CLOSE Left , over and over in sync with the signal on the television. That creates the 3D effect. Like profholt said, if you could blink your eyes really fast you could do it as well.

Since the tech is the same, you can use different goggles with the adapters if the phono plug fits and works. I'm not sure why there would be too much variance, maybe the speed in which the glasses respond to the commands are different? I never noticed much of a difference personally, it was just the comfort level of the glasses in question.

Here are the ASUS ones I've got: http://www.ebay.com/itm/ASUS-3-d-Mon...-/262282409297

Ah, thanks, that actually cleared up a lot of things for me. So, the bottom line is, no matter what glasses you use, you'll always need the Sega 3D adapter to plug them in and connect them with the console, is that right?

Welll, in short, yes you need the adapter to make it work.

At least that is what I have been lead to believe, that it is specific to whichever consoles adapter you are using.

However, after doing a bit of research I think that it really is using just the sync off the video either way to time the open/close, so you could make your own.

The nvidia glasses will work, but you need a program to tell the nvidia transmitter to transmit a signal, and from there you connect the VESA cable to the Master System 3D adaptor.

I only tested it very briefly, and it seemed to work fine. The computer is required for the emitter to work only, it simply tells it to emit a signal, and with a VESA sync connected, itll output what it is told to from there.

I just found out that there was a 3d adapter for the playstation 2. I picked one up from amazon and the glasses work great so far on the master system. The price has gone up since I got it but if you have a ps2 it might be worth it https://www.amazon.com/gp/offer-list...&condition=new

Since I just see this thread, something worth noting: the 3D glasses in the Master System don't rely on the video signal, just on the game telling them which eye to display (which thankfully is much simpler and reliable). If you have any delay issues, it likely means the glasses are too slow (too fast will never be a problem).

A bigger problem is that they only will work with CRT TVs. Anything newer will introduce lag and even a bit of lag will be enough to completely ruin the effect.

I used Nvidia's shutter glasses ages ago in a computer store that had some version of CoD or Quake Wars on demo. The effect was pretty good, but since then, I've never laid eyes on a pair of shutter glasses, even at rummage or yardsales. Alas, the red/cyan glasses used for games like Rad Racer and 3D World Runner do nothing for me, as I had trained myself to be cross-dominant for shooting purposes. I can consciously ignore the input from either eye, but I have a hard time equalizing the input for more than a few seconds at a time. Ah well, second amendment problems.

It seems like there's one model of wired 3D LCD shutter glasses compatible with the SMS being sold on Amazon and Ebay these days. Unfortunately, there's only one vendor at the moment, 3dtvcorp, and their prices aren't what I'd hope. Still, might be something to consider, for folks who already have the card slot adapter (which is of course required).

Example: https://www.amazon.com/Shutter-glass...dp/B017KQGEW4/

If you use a Mark III SMS the adapter is built-in.

I had those, they worked poorly. Found the ASUS glasses and those work pretty near close to the SEGA originals.

Sorry to hear that. I'm seriously tempted to just hack together new arms (or equivalent) for my Sega 3-D glasses, myself (having already mended/rebuilt one broken arm with a little ABS plastic carving). I've got a fairly large head for an adult man, and there's only so long I can wear them. I feel like maybe replacing the arms with just a hinge pipe + strap would be the best approach.

So I did end up acting upon the issue of the excessive tightness of the arms of the OEM glasses. My solution worked out ideally, and yet was utterly simplistic. I simply (whilst listening to an audiobook) for about 25 minutes non-stop, exerted pressure at points along the arms of the glasses, slowly working across each arm's entire length time and again and again, decreasing their curvature by the tiniest of margins with each sequence of presses/massages, until they approached straightness, and placed essentially no pressure on my head. There is no evidence of structural damage to the plastic, and the (almost absent) curvature looks entirely "natural". Because with the arms nearly straight, the glasses can no longer "fold" beneath one another (they're too "long", when straight), I also took the measure of shortening each arm by about 5mm, with some snippers and a dremel. I don't feel bad about physically modifying these glasses, as they were already "damaged" when I acquired them (one arm broken), and one hinge is already my own transplant. So it's not as if a perfect condition item is being robbed of that status.
