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?
