Hmm, interesting. Are there any other games that change palettes based on hardware played on? I'd like to get my hands on those restoration patches. No reason to play a brightened palette on a backlit screen.

Backlit make it sound like you're talking about the AGS-101. What I said doesn't apply to the AGS-101, it's completely different.

How do GB and GBC games work on an AGS-101 compared to a GameBoy Color?

Shinybow SB-2840 (RGBs SCART to Component YPbPr converter), the specs for output say "SDTV 480i (13.50MHz)". Can this output 240p (I know they're kinda the same signal, just want to make sure my 240p from my NES and SNES will look how they should with more noticeable scanlines and such - when hooked up to my consumer SD Sony Wega).

Yes, the Shinybow transcoder handles 240p just fine.

I've never seen an AGS-101, but from what I gathered, colors are oversaturated and the interlaced refresh is gone.

Oversaturated? How do you figure that?

And yeah, interlaced refresh being gone makes sense. Apparently the AGS-101 has a slightly higher response time, resulting in some faint ghosting.

I know the GameBoy Micro only supports GBA games, but I wonder how it's screen compares to the AGS-101.

It's not that, it's about the light spectrum that passes through the screen.

I wouldn't say that's the case. A lot of the SNES ports like Super Mario World, Yoshi's Island, etc. that were released early in the GBA's lifespan all had their color palettes significantly brightened to account for the original GameBoy Advance's unlit screen. The bright color palettes of the SNES ports are terrible on every display, just less noticeable on an original GameBoy Advance.

Then you have games like The Minish Cap that was released in November 2004, over a year and a half after the release of the GameBoy Advance SP AGS-001. It featured three different brightness settings to accomodate for different screen types.

From my experience with them Nintendo didn't get something quite right with the lighting. The backlight color (or possibly the LCDs themselves) have a pretty wide range of temperatures. The two I own, both secondhand mind you, range from slightly blue to slightly pink. I could probably do a color test on them if anyone cares and we have a testing rom.

Better get cracking on that test rom then.

Any recommendations on a quality MALE to FEMALE SCART cable, about 6-10 feet long (2ish meters). USA supplier would be good, but if shipping is decent from overseas that's fine too.

There's a bunch of super-cheap ones on eBay - just don't know if the quality is good. I'm pairing these with a cable from Retro Gaming Cables which only came in 6' length and I need to extend it roughly 6' longer.

hard to find and almost impossible to know what's the quality before trying. I would use a (good) regular male to male cable and a F2F coupler to connect them.

Good Idea! Ordering a coupler now.

We need the 21 pin variety, correct? (they seem to be sold as either 20 or 21...)

it's the same. Pin 21 is the outer metal surrounding.

Thanks once again. Ordered two of them along with 2x 12' male to male cables.


Question: I know it's OK to stack a 20" pvm on top of another without damaging either of them, but what if the one on the bottom is turned on its side (TATE)? I don't want to possibly crush one of these by placing a 20" on top of the one on its side (and the side doesn't seem to be quite as rigid as the top...).

I don't think that the wires holding the mask in place are affected by forces exterted on the external frame? I know that they are susceptible from physical shocks/impact though.

On another note, does anyone know if the Kramer FC4043 cv/yc/component transcoder works with 240p signals?

Edit: Sorry, I inadvertedly edited this previous post while trying to make a new one.

The best way to find out is to open the case and see what kind of bracing is built into the chassis. My Sonys are pretty sturdy in each direction but my JVC isn't.

The colors are slightly different. That's about it. The interlaced refresh may be more noticeable than before.
Is it just a constant value added to the pixel intensity value? I'm wondering if there's an easy fix I can implement for my GBA (AGB-001) to TV adapter.

What do you mean by interlaced refresh, is that special mode that not all games use? For most of the games I've tested, they seem to be progressive (each line is sent consecutively, no even/odd ordering). I would think that if the games were interlaced, that I would see errors in the video output based on how I'm buffering the video/outputting it to display.

It's at minimum an exponentiation, a 3x3 matrix multiplication, and another exponentiation. This can be simplified with 1D LUTs or a 3D LUT for the whole.

It's built into the screen.

Thanks for the clarification. I'm not familiar with 3D LUTs for image processing, but I'll definitely look into it.

With a CYP CPCD‑41AR VGA switch can I potentially switch between one Scart RGBS signal and another component one? With the help of something like SyncStrike and/or Extron RGB interface and a simple component to VGA adapter for example

No one had a chance to try out one of these? There's one up for sale on ebay Italy right now, but it's a bit too expensive to try my luck.

And sorry but I've got another question :oops: this time on the Extron DVI to RGB transcoder (here's the User Manual). It has an EDID switch that allows to either select a desired resolution among ~15 (one more can be customised) or let the job to a 2nd monitor connected to the loop-through DVI output (edit: of course we're talking a resolution to be asked to an hypothetical graphic card or other compatible source, no scaling/processing). Now, let's say I hook up an OSSC to this thing to have an analog out - do you think I'd have to come to terms with the embedded EDID/resolution selector or can I just put the switch on 'monitor' while actually not connecting anything to the DVI pass-through (just a CRT on the analog out which is what I'm after)?

definitely. The OSSC doesn't require (or read) a monitor's EDID information anyway.

The Extron DVI to VGA demands that you use DVI mode.

It doesn't do any HDCP content. It also has some jitter and ringing.

I strongly dislike the Extron DVI to VGA boxes. I think they were overpriced crap. Don't buy one.
We apologise for the inconvenience
