Sony XBR850D and the SNES - looking for upscaling solutions...

Well, let me preface things by saying I think I'm looking for upscaling or sync fixing solutions. I'm not entirely sure what the best route to go is. Here's the story:

So the Fiancé and I bought a new Sony XBR850D TV on Black Friday after a ton of research. On paper it seemed to have everything we were looking for, low input lag, component inputs for my old school game systems, and an android OS packed with her neat little games and my arcade emulators.

Well I set it up, updated it and immediately measured the input lag in game mode against my NEC XM29 CRT- ~17ms, half of what it was measured at by RTINGS, and perfectly acceptable for my purposes. The Android OS ran wonderfully and every app we wanted worked flawlessly.

Finally I tested my old game systems using HD Retrovision Component cables. Nothing Nintendo based that produces a 240p image seems to work properly. Works through Composite in any source, and it's probably the best upscalling of composite I've ever seen, but it still looks quite awful. I can get some other 240p systems (like the Genesis) to work on component however, and it's not like no image is produced. Occasionally, a stretched version the image appears for a few seconds as the TV struggles with what I'm assuming is sync. When it does display an image, it says it's 480i, and sadly, it looks pretty good for those few moments.

My old TV (an especially input laggy Toshiba) displayed a flawless component picture, and my CRT displays a flawless picture with the cables as well, so it's definitely not the cables. After a bit of Googling online, apparently this is a common problem with Sonys.

So now I'm at a crossroads. I'm not returning the TV over my retro systems not working on it, but I would like to have the option to play some slower paced games on it, especially the SNES library. I know I could buy a Framemiester, but I was wondering if there was a cheaper or simpler option considering I only need to fix what I'm assuming is sync.

Has anyone run into / solved this problem before?

 

There are some cheap scalers out there but then you would be introuduce alot more lag. I'd recommend the XRGB just for speed reasons alone. The ultimate setup however is an OSSC + VP50 Pro

 

The OSSC is a name that keeps popping up a lot, but there's mixed reviews as to whether it works with Sony TVs. Some say it needs to be used with another processor while others say all the sync issues are resolved with SNES. I'm assuming the VP50 Pro is another processor?

Edit: ...Should have googled first, I see it handles non standard NTSC signals (like the SNESs) without much input lag. I get it, it takes care of that portion. Hmm.

 

Sync issues are not resolved with the SNES becuase the OSSC has no framebuffer. It just depends how your TV likes the hdmi signal with a non standard sync. You could not use an OSSC and just use an VP50 Pro and have no problems.

But an XRGB is still going to be the best and most practical solution. New tv's are just not designed for old tech like this.
