These are some crappy cellphone camera grabs of my Famicom + AV mod going into an XRGB3 to my 60" TV.



Now, take the XRGB3 out of the picture and use a cheap 35-40$ composite upscaler, and you're getting this kind of image, for less than half the price of the thing. If you already had an XRGB or something for other purposes, you can just exclude it altogether and enjoy NES on bigTV9000 for <100$
I saw the quality of this thing in action in an AnalogueThingy. It outputs and looks nice. However, for the price, I think it's a waste. It's NES.
Even the crispest, greatest NES image of all time is not that great. It's NES. There's not enough colors per tile to really benefit from this stuff.
Composite upscaled eliminates artifacts/smudgies, and is crisp + scanliney. I could probably make the above images look better if I cared enough. I didn't bother tweaking settings in the XRG3.
So you're only really going to benefit from this mod if you're some kind of NES fanboy, you have a boner for overpriced hardware (the AnalogueThing), or you never intend to do anything upscaley with any other machine.
oh, and there is no input lag in this case. I'm sure someone will bring that up. I sit and blow through Legend of Kage ad naseum.
You can't do that with input lag. That's not a thing that people do.
So, what I am ultimately getting at here is, the mod is nice enough for what it is, but the price is batshit insane.
