OSSC V1.8: retro console images on a modern screen, with no lag
The OSSC (Open Source Scan Converter) is an open-source converter that multiplies the lines of the retro console signal instead of storing and resizing whole frames: the result is no added lag. This product page offers the OSSC V1.8 and, as a separate variant, an add-on board that accepts composite and S-Video.
What it does
- Line multiplication: doubles to quintuples the lines of 240p and 288p signals, for a sharp image on an HDMI screen.
- RGB inputs: RGB SCART, component (YPbPr) and VGA, in 240p, 288p, 480i, 576i, 480p and 576p.
- Up-to-date firmware: updated via SD card, according to the supplier.
- Add-on board (separate variant): accepts composite and S-Video, with line doubling and smoothing modes, and outputs SCART or component to the OSSC.
What it doesn't do
- The OSSC alone accepts neither composite nor S-Video: you need a console in RGB or component, or the add-on board.
- It does not turn everything into “standard” 1080p or 4K: high multiplication modes produce timings that some TVs reject.
- 480i and 576i are deinterlaced simply, with some slight flicker possible.
- The two variants are separate devices: choosing the add-on board does not deliver the OSSC, and vice versa.
Compatibility
Retro consoles outputting RGB SCART, component or VGA: Mega Drive, Saturn, Super Nintendo, PlayStation, PS2, Dreamcast, Neo Geo and many others, with the right cable. Consoles limited to composite or S-Video (an unmodified N64, for example) go through the add-on board. A TV that is too strict about timings may reject some modes: plan to try several settings.
Skill level required
No soldering. You do, however, need to choose the right cable for each console and get to grips with the OSSC menus (multiplication mode, sampling, sync). Allow a little setup time per console to get the cleanest image.

The job: a sharp image with no delay
Plugged directly into a modern TV, a 240p console gives a blurry image and an annoying delay in reflex games. The OSSC sits between the console and the screen: you connect the RGB or component cable, choose the multiplication mode, and the image becomes sharp with no added delay between the controller and the screen.
The part: a recognised open-source converter
The OSSC is an open hardware and software project that has become a reference among retro gamers for its zero lag. Its firmware keeps evolving and is updated via SD card. The add-on board offered as a variant fills its only real gap: the lack of composite and S-Video inputs.
Support: getting the settings right
The OSSC is set up console by console: multiplication mode, sampling phase, sync. Start with line doubling, accepted by almost all screens, then work your way up. If your TV rejects a mode, our customer service replies within 1 business day to look for the right setting.

Frequently Asked Questions
⚡ Does the OSSC add lag?
No. It works line by line without storing a whole frame, which adds no perceptible lag.
🎮 Which consoles can I connect?
Any console that outputs RGB SCART, component or VGA, with the right cable. Consoles limited to composite or S-Video go through the add-on board.
🧩 What is the add-on board for?
It accepts composite and S-Video, which the OSSC does not handle, offers line doubling and smoothing modes, and outputs SCART or component to the OSSC.
📺 Will my TV display all the modes?
Not necessarily. High multiplication modes produce non-standard timings that some screens reject. Line doubling works almost everywhere.
📦 What is in the box?
Depending on the variant: the OSSC V1.8, or the add-on board. Power supply, console cables and HDMI cable are not guaranteed.
🔧 Do I need to solder or open anything?
No. Everything connects by cable. The real work is setting up the menus for each console.
🚚 What are the delivery times?
Delivery in 10 to 18 days, dispatched within 3 to 5 days.
🛡️ What guarantee applies?
2-year legal guarantee of conformity. 14-day returns. Customer service replies within 1 business day.
Why buy here rather than on a marketplace
It is a fair question. Here is the answer, straight.
Every listing is checked before publication: real compatibility, material, dimensions, box contents. Many models never make it into the catalogue.
A question about compatibility, a fit problem, a return: you write, a human replies within 1 business day. In French.
The 2-year legal warranty of conformity is handled by us — not by a form on the other side of the world. And 14 days to change your mind, with no need to justify yourself.
We do not claim to be the cheapest. We claim that you will know exactly what you are buying before you pay.
