SOLD OUT – Don’t try to cheat the page and order, I can’t sell you units I don’t have! You can still get a 1.6 here.

These are refurbished units, sometimes repaired customer returns or units that were DOA from the factory. The units are in like new condition and come with 6 months warranty. The packaging may show some signs of wear and the anti-static bags may have been replaced. They do NOT contain the digital audio upgrade boards, that means analogue audio only.


Important! – We give you the option to purchase the OSSC without power supply unit (PSU) or remote, so that you can use suitable replacements you may already have yourself. Information on using alternative remotes is available here. Please note the specs of the required PSU carefully. You require a unit that outputs DC 5V with at least 1 Amp. The tip must be 2.1 x 5.5mm and centre positive. Please note that damage caused by using an incorrect PSU is not covered under the warranty.

Need a different number of accessories? Do you want 2 power supplies but only one remote, or a spare remote perhaps? Leave the boxes above un-checked and add additional power supplies here or remotes here. For quantities greater than 6 OSSC units please contact us.

Customers in Asia please note – RGB cables are wired slightly differently in your region (despite having the same physical connectors). If you want to use JP21 RGB cables with your OSSC, please also order a JP21 adapter. This adapter is NOT required for the more common Euro SCART cables (as purchased from, Retro Console Accessories or most dealers in the EU, Australia and America).

It’s finally here! The ultimate lag-free retro gaming linedoubler and processor hits the market. Now there’s an affordable way to use your retro consoles on your PC monitor or TV in perfect quality. No more bad upscaling, no more interlacing artefacts, no more high input lag, the OSSC is a dream for retro gamers and collectors!

What does it do?

Processes (line doubles) retro games with NO input lag – Unlike other scalers, such as the XRGB Mini, the OSSC works on individual scanlines rather than a frame at a time, that means there’s no input lag whatsoever (well, a few nanoseconds if you really want to be precise).

Eliminates ugly deinterlacing artefacts and bad scaling – Connect most retro consoles to your TV and if you get a picture at all, it’s likely to be ugly. Bad scaling combined with deinterlacing (which should never even be applied to 240p material) will ruin the picture and make you wish you had your old CRT back. Well, worry no more! OSSC converts the image into a 480p or 720p (where compatible) image that is correctly displayed and processed. EVERY special effect, from 240p drop shadows to striped sprites, is rendered correctly.

Converts SCART and Component to DVI/HDMI – Feed in a 480p component video signal from a Wii and get out a perfectly processed 480p HDMI or DVI (with a simple adapter) image. The quality is flawless!

Convert VGA to DVI/HDMI – Connect a Dreamcast directly to the unit and enjoy HDMI processing of all your games, not just those that support 480p.

Convert analogue audio to digital DVI/HDMI *NEW* – Analogue audio from your retro games console will be converted to digital audio and injected into the HDMI/DVI output (requires compatible TV, processor or AV receiver. Analogue audio output is still available for setups where this is required).

Fast deinterlacer – Fed up with high input lag on interlace games? The OSSCs deinterlacer is lag free! Note that this does however mean there’s a drop in picture quality for interlace sources, but this is unavoidable. A pass through mode, where interlace signals are sent directly to the TV for processing instead, is also included.

A Worthy Investment

I've had my OSSC since December of last year and it's been an absolute blast. All output modes work perfectly on my BenQ RL2455HM monitor and the image quality for both my Saturn and PS2 (when using progressive video modes) is absolutely pristine.
My only real complaint is the lack of a more sophisticated deinterlacing method, as the flickering caused by bob deinterlacing can be quite distracting. I'd definitely be willing to buy another unit if they ever make a new revision with hardware capable of utilizing better deinterlacing solutions.

Link to the past looks great

The conversion looks great (my snes looked like butt with the standard converters). More importantly they STAND BY THEIR PRODUCT. My first unit was defective and they shipped me a new one promptly after receiving the defective unit. Appreciated the quick communication, and prompt shipping.

New Wave Of Retro Gaming!

I've been using the OSSC for about a year now and couldn't be happier! After some twiddling with the many options of the OSSC and a few adjustments to my TV's settings (which by default didn't give the optimal picture for any of my applications, including my PC and disabled all the optimizations), my Japanese Mega Drive output looks better than ever (also thanks to a good RGB SCART cable). Thanks to a vivid picture with nice colors and blacks and of course the scanlines, give a classic arcade-like experience on my 4K TV, which is great. Recommended!

OSSC - the best of the best!

Finally, I got the best picture for Playstation 2!
XRGB-mini Framemeister could not do this!

Thanks Sergey! While we're glad you love the OSSC, for the PS2 the XRGB-mini is usually the better choice, since the OSSC does not have sophisticated deinterlacing and most PS2 games run in 480i.

OSSC Works great

Works great with a little cheap magnovox tv, (19mf1377b usa model) actually works with snes on all resolutions. Doesnt work with my 75xbr900e 4k with snes but works with the sega genesis (megadrive). However the snes works with tv if im connected thru my av receiver marantz sr6010. I am extremely happy and it is a big upgrade over the cheap scart to hdmi converter.
