GBS-C AIO Scaler


The GBS-C AIO is an addon board for the GBSControl by ramapcsx2 and others. The GBS-C AIO is by far one of the most feature packed and easy to use scalers for retro gaming and retro computing – high quality scaling has never looked so good!


  • Very low lag, less than 1 frame.
  • High quality upscaling for nearly all retro game systems and computers – anything pre 2000s.
  • Fast resolution switching between 240p and 480i video signals – output to the display never drops sync.
  • Motion Adaptive deinterlacer that engages automatically and is superior to most BOB deinterlacing and BOB deinterlacing is available should you want it.
  • Easy to navigate interface via web browser.
  • Color reproduction with auto gain and auto offset for the triple 8 bit @ 160MHz ADC.
  • Zero Lag bypass capability for transcoding video.
  • Simplified power management compared to other DYI GBS-C set ups.
  • PCB style enclosure.
  • Inputs: SCART(RGBS), Component (YPbPr), VGA(RGBHV).
  • Outputs: VGA/YPbPr 1280×960, 1280×1024, 1280×720,1920×1080, 720×480/768×576 and Source Pass-through.HDMI 720P/1080P. only one VGA or HDMI output at a time on the GBS8200.
  • Fast downscaling at 240P via VGA/YPbPr.
  • Built in Sync Strike that can be turned on and off.

We’ve hand assembled a small amount of GBS-C AIO units as we enjoy this scaler and realised that it isn’t readily available for purchase anywhere. All units shown as in stock are ready to ship.
