(There's a little bit of ringing though, don't know if it's coming from the Sony or the AA)
can't say that I noticed it. horizontally or vertically ?
Do other transcoders (like the FC-14 or TC1600) feature ratio or V&H size compensation without killing the picture quality ?
no, you can't do this by transcoding. The Crescendo has potis for shifting, but you cannot scale (as in AR control). If you want scaling you're back to using a secondary processor.

Vertically. But it's nothing big.
I can live with it.

Okay then, the AA's already got h-shift and I don't really need v-shift.
Glad to finally be able to wire RGBHV devices to the W6, without crappy scaling artifacts nor lag.
By bye wobbly/wavy effects and ugly checkered patterns. :P

I didn't have a chance to try a XRGB-2 transcoded on the Sony. Completely stable ?

Only tried for about five minutes with only the MD and nothing went wrong, all silky-smooth.
I'll do more testing later tonight (no I'm not watching football :twisted: ) and during the week-end.

Just tried the Comm-Tec UP 1280 -> it is like a new machine ! :!:

Just did a run of Thunder Force III and a bit of Steel Empire to fine-tune the MD/XRGB-2/AA/W6 chain.

This is what I've noticed;
- there are slight scrolling hiccups, but barely noticeable (NB: this is a PAL MD2 w/ 60Hz switch)
- the 'jailbars' once visible on some background colors, are gone.
- some color bleeding visible on the typical MD 'outside frame' when it's not black.

I have much more stuff to try, but I'm already impressed with the results.
Not ready to sell my DVDOs though, since those have nice 'pros' I would miss too much.

The most interesting fact about the whole trancoding business is that you realize how wrong "VGA" has been handled all those years.

Really wrong indeed. What a waste.

Anything the Gefen VGA to DVI Scaler Plus does better than a transcoder like the AA ?

The Gefen can resolve the full 720x480 resolution, but the AR will be too wide. Kinda the opposite of what your TV does on it's own. About 1.5:1 I'd say.

Any ETA on the transcoder guide, Fudoh?

If you could feature a breakdown of the various Kramer FC-4XXX models and their feature breakdowns, that'd be great.

I did run across the discussion where somebody warned you off the Kramer FC-4040. I'm still not convinced that was right (I'm going to have to dig into mine a bit more).

Sorry, I'll only include the smaller units (FC-14 and 15).

This was the thread on the 404x units: http://shmups.system11.org/viewtopic.ph ... hilit=4042

You know those cables that has a thicker part where one can store potensial components that the ends of the cable cannot? What are they called?

Ferrite cores (for noise/parasite suppression).

Okey, I am mostly interested in the plastic part so I can stuff things there, anyone know where I can buy those?

No, but I made a custom cable after busting open an old 3rd party RF adapter. It had pins for every contact point, even though the RF adapter only needed 3 or 4. I removed those pins and put them in an official AV cable, which are a lot easier to open (just push in the 4 tabs on the bottom).

I'm sure if you're more gentle than I was, you can actually use the connector from a 3rd party RF adapter. Maybe use a small dremel if there is no way to pry it open.

Could anyone explain to me what exactly is 15 khz / 24 khz / 31 khz displays ? Do these just correspond with certain display resolutions?

I'm checking my local classifieds for CRTs but I'm unsure how to be sure if the displays are able to do 15 khz.

Rule of thumb. PC monitors do not do 15khz, but do 31khz. Consumer CRT televisions and pro CRT displays do 15khz but very rarely do 31khz. Almost nothing does 24khz.

the different khz are the horizontal refresh rate of the monitor, which practically speaking means resolution. 15 khz = 240p/480i, 31khz = 480p. Any consumer CRT you buy will be 15 khz only, unless it's a digital one in which case they usually take up to 1080i (though may not be able to resolve the full horizontal resolution of 1080i).

By consumer CRT do you mean SD CRTs? Do newer HDCRTs do 240p normally ? or, how old of a model should I be looking at?

24khz is 384p, which you'll find on some arcade boards, e.g. Sega's Model 2 and 3 games.

The Pioneer 4:3 plasma sets accept 24khz natively, but other than that, what's been said is right - you'll hardly find 24khz support out there on any consumer hardware.

I still had it from when I got it in junior high. They're all over the net though. Should be super cheap. Like this one on ebay for example:

HD CRT's are not a good choice for displaying 15khz content. Any ordinary SD CRT TV should do the job. Stick to quality Japanese brands like SONY. The newer the set the better, just stay clear of the HD models, which should be easy as they were rare anyway, especially in Canada.

If you insist on having a HDTV for all gaming consoles, you should get a XRGB-2, 3, or Framemeister.

All I can find is HD CRTs!

I'm actually trying to pick up a CRT for building a mame cab. I've got my upscaling for my main TV under control :) Although I'm cheap and use a lenkeng, it does the trick pretty well.

Is it possible to play, say, Galactic Attack (or any other US/NA game) on a Japanese Sega Saturn via an Action Replay 4M Plus cart? Has anybody tried it for themselves?

EDIT: Nevermind! (it works)

I've a question, given I'm about to start saving up for a Supergun: what is recommended in regards to playing medium-res arcade games on an NEC presentation CRT capable of every horizontal scan rate OTHER than 25KHz? I really want to look into a System-24 Bonanza Bros. board, but my monitor can't accept that rate (but can pass it through to a capture card that can).

Yes, yes, and maybe 2003-ish. If it's widescreen, it's an HD CRT, steer clear of those if you're only buying it for 240p consoles, as I've heard things look very weird on such a high resolution tube. Just look for a flat screen (unless you prefer the curved ones), 4:3 CRT and make sure it's not something like a hi-scan Sony Trinitron, which I believe had a high(er) resolution tube.

Most every 4:3 CRT you find will be SD.
