I'm looking for a good line doubler to for retro gaming use. Basically it could be anything that inputs 480i and outputs 480p, but must not add lag.

An Extron Andora would be perfect. I've heard people here say that it looks horrible because it combines fields and line doubles without any deinterlacing or processing to prevent motion feathering. Obviously this is normally true, but I'll be running the output through an Extron Super Emotia to downscale to 240p, so the feathering won't be visible. Most importantly, the lack of processing means there is literally no lag, which is important for gaming.

Unfortunately, I haven't been able to find an Andora. I've had a WTB posted here and elsewhere for a while with no response, and an automatic eBay search has yet to yield anything.

The reason for all this is that there are certain games that were originally designed for 240p, but run on the game console upscaled to 480i. The Super Emotia forces things back to 240p, which looks much better for if the source material originally intended it. I already have a Super Emotia, and this is working great, but it only accepts 480p and I need a better scaler that's lag free.

Does anyone know of any good alternatives? There are plenty of digital scalers that will do this, but they generally add at least 2 frames of lag. So I'm looking for a simple analog line doubler like the Andora, or something that can somehow scale digitally without lag. Anyone?

lol, yes I know. That's what originally pointed me to the Andora and the Super Emotia. Specifically, it was the sister page to that one:

http://scanlines.hazard-city.de/

I talk to him often on the shmups forum, in fact I talked to him earlier today!

Anyhow, he recommends the Andora, but I've been unable to find one. Anyone know of a good alternative?

Depending on what you would like to spend an older XRGB would be your only alternative. Zero lag, brilliant quality. Probably around $160.

Fudoh, previously you recommended the XRGB-2, but I don't think we got into too much detail. Out of the 1, 2, 2+, 3, and Mini, which ones would be suitable for this application with zero lag, not even the normal two frames?

I was looking to see if anyone knew of a good alternative to an Andora (or if I could find an Andora). An XRGB sounds like overkill, but if I can't find anything else then I'll have to bite the bullet.

all of them (though I never had a mid-90s "1" model).

You mean that you'd like to sell?

no, sorry, nothing for sale. But a 2 or 2plus should not be too hard to pick up.

Sorry, I misread that.

I thought you said "all of them (though I have a mid-90s "1" model)." I thought you were emphasizing that one because you had one to sell. I was in a hurry this morning.

I wonder if there's any chance of getting this one working:

http://www.ebay.com/itm/330768494588?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649#ht_500wt_1414

My guess is either:

1. The RGB input is fine, and he was using the wrong pinout.

2. He knows exactly what's wrong with it and isn't saying.

na, you didn't misread. Was a typo and I fixed it afterwards.

The XRGB you linked is blown. Somebody used a Euro-Scart RGB cable on it... If you're REALLY good with electronics it might be fixable by replacing an IC. Moosmann did succeed in repairing a blown XRGB-2plus over here, but it wasn't easy.

An IC in a socket or an IC that needs to be desoldered from the board? Haha, if you're saying it's difficult then I guess it's the latter. I don't have the equipment for that, so I suppose I'll pass on that one.
