I’ve personally had really good luck w/ NaOH, but the trick is that you need to use a very strong concentration of it, plus heat (it should be solid at room temp, but melt when heated). Leave it on there for a little bit, and the coating will start to dissolve. I’m not familiar with oven cleaner, but the cheap drain cleaner that I picked up at the hardware store is 100% NaOH (no weapons grade necessary 😛 ). There’s also some adhesive below the coating, which I usually remove with goof off.

The last display I did, I tried the “no-chemical” method, but I wasn’t satisfied with how it was working, so I used NaOH to dissolve the cable, then soldered it, and it turned out really nice. But, as the video shows, it’s certainly possible to do.

That kinda 3D has been around for a long time though… arcade games like Police 911 ( http://www.youtube.com/watch?v=G4__ssaLrTo ) used it. IMO the part of the 3DS that excites me is the display. We’ve already seen that a plain DSi can change view depending on head position, and there’s really nothing technically challenging about changing the viewpoint… the hardest part is properly tracking the head, which just takes a camera and some software.

BTW, if anyone is looking to do head tracking on a PC, FreeTrack ( http://www.free-track.net/english/ ) works really well (and is free). Just install some LEDs on a hat, glasses, etc, connect a webcam, and go. For better performance, I modified my webcam (removed the IR filter, then covered the lens with the magnetic portion of a floppy to only pass IR), though it’s not necessary.

That’s pretty funny… kinda reminds me of this: http://www.youtube.com/user/franklynews#p/u/1/iRM0Q8QCelA … a local Realtor which does a video blog with a camera attached to his steering wheel.

Cool… congrats, though that’s an odd set, being a “collection of US released games”, though not all US versions. Do you plan on getting all US versions eventually?

The US version of Jack Bros is better IMO (since there’s quite a bit of text, though none really important)… and last I knew, Vertical Force US wasn’t too expensive. How about JP only games? I see you’ve got Space Squash (good choice)… any plans for others, like Virtual Fishing, Insmouse, or others?

It’s actually pretty easy, and I did it for pretty cheap. I got the computer for $60, the video card for another $60, the projectors for $75 each, and the silver screen (40″) for $20 (all on Craigslist).

Then I used lenses from cheap linearly polarized glasses in front of the projectors to polarize the light, and of course wear polarized glasses. The projectors are LCDs (at 1024×768), though I’ve heard some LCDs won’t work… these don’t work with circularly polarized lenses. I just stacked the projectors on top of each other, and they’re pretty thin, so there’s not much angle difference, so the images merge well.

I just used one dual-head video card, and used the iZ3D driver ( http://www.iz3d.com/ ). I’ve been using demos of the drivers, though I’ll be purchasing it soon ($50).

Now that it’s set up, it’s really easy to use… just turn on the computer, projectors, put my glasses on, put my tracking hat on (for head tracking), and play 🙂 . Totally worth it 😉 .

I’m tempted to try one of these too: http://www.vuzix.com/iwear/products_vr920.html . The resolution is a little low, but if it works well, I’ll bet it’s still pretty cool.

Yeah… also, one difference between mine and yours is that mine uses 3 equally distributed fixed shades of gray… of course it could be optimized to look better with different shades of gray.

DogP

I’ve had several Neo Geo cabs, though they’re pretty big and I don’t really like many of the games, so I’ve never kept any of them for very long. I do still have one of the small gold cabs (like: http://www.hardmvs.com/xml/usa/MVS-2-19/MVS-2-19b.jpg ), though I guess it’s kinda irrelevent to this post, since that one isn’t red 😛 .

I don’t really play many PC games, but my “gaming PC” is a Pentium D 2.8GHz w/ 2GB RAM (I think) and a GeForce GTS 250. I use a dual projector setup with polarized lenses/glasses for 3D with a modified webcam for head tracking. I haven’t found any games worth buying in many years, so I pretty much just play whatever demos can keep my interest for a few minutes… my favorite being Tom Clancy’s H.A.W.X.

That looks nice, but I think there’s too much detail/random noise… I doubt you’d be able to convert that to chars/bgmap (or it’d fill up almost all the Char RAM).

I convert my images in Photoshop, and if I do it with diffusion, it looks nice, but most large images run out of chars… but with pattern, there’s usually quite a few chars that are identical, which of course is good for us. Here’s an example added to the right of yours.

Yeah, it’s been discussed quite a few times recently… there’s a time limit on editing your post (30 mins I believe). Basically, if you post, but forget something, then edit it rather than double posting. But for everything else, reply to the post.

Correct… there aren’t any factory sealed boxed Mario’s Tennis’, in either region.

The “vbWaitFrame” function that comes with the Wiki Sample Code (and the PVB Coding Competition logo code), which uses the XPSTTS register, is fundamentally flawed and should not be used in new code.

I’d recommend a calibrated delay function, like I used in my audio apps. Using a hardware timer is a waste of resources IMO (and not compatible with code already using the timer for something else). It’s not necessary since you’d just be using the CPU to poll the timer, rather than just using the CPU to count however long it wants to delay (if you know how many CPU cycles it takes to execute a chunk of code, you know how long that delay is).

The hardware timer is nice because it can run in the “background”, and either interrupt, or just have the CPU check it on occasion while doing other stuff.

I also don’t like the name “waitframe”, as it makes it sound as if it’s waiting a certain number of display or game frames (which makes a non-deterministic delay unless you know where in the first frame you are when executing the function), but its common use is as a general delay function. I’d rather have delay_ms(), which delays a specified number of milliseconds, and have a waitframe() function wait for the next game frame (so you can just call that function at the end of your main loop to sync everything to 50Hz).

One thing I really wish the V810 had is a free running counter though. They make delays, profiling execution time, etc. so much easier.

Cool… sounds kinda like Castle Quest.

I made a pinout of it a long time ago, but IIRC almost all the pins were shifted by one pin from the final.

DogP

Heheheh… that’s kinda funny… I can’t believe he individually inserted PCMCIA pins into the cart 😛 .

He also tried to leverage himself as a needless middle man in many deals, including a deal involving DogP’s Faceball.

I just want to clarify that it’s not my Faceball, but as I told you (and “Sam Gupta”, who died in an earthquake in Mumbai – R.I.P. :rolleyes ) in the emails, that I could work a deal for it, in trade for the Zero Racers source code you claimed to have. Too bad it was obviously just Bound High source code, with some files renamed.

I guess I was kinda a needless middle man as well (except I would have likely been the one trying to compile it), but the owner trusts me, and without my knowledge/judgement, may have been scammed into buying/trading for your “repackaged” source code.

My deal for faceball was very real. I’m hoping this doesn’t end up being known to my faceball source or I’m sure the deal will be off.

I really doubt your deal for Faceball was real (and shouldn’t it have been “is”, not “was”)… and usually a deal has to be on before a deal is off.

Before I did this there was not a known working version of the game and very few people even had the shit version.

There’s actually been a working version known for many years, just apparently not by you.

Heh… yeah, I’ve got about 9% of the posts 🙂 . And I didn’t notice until I checked the forums a few times (since posts here are pretty slow), but a number like 10000 kinda sticks out 😛 .
