Other

  • Neo Geo AES – RGB SCART
  • TurboGrafx-16 / PC Engine – RGB mod required
  • Arcade Boards (JAMMA, CPS2, etc.) – RGBS / RGBHV direct input

Supported Inputs

  • RGBS (SCART or BNC)
  • RGSB (sync on green)
  • RGBHV (VGA)
  • YPbPr (Component Video)
  • Composite (CVBS / AV) – supported, but image is typically darker and softer
  • S-Video (Y/C) – supported, but picture can appear dim or lower quality than expected

Supported Outputs

  • HDMI – digital output up to 1080p60
  • VGA (RGBHV)
  • RGBS (analoguee)
  • YPbPr (Component)

Resolution & Scaling

  • Upscaling: up to 1080p60 (line-doubling, scaling, deinterlacing)
  • Downscaling: down to 240p/288p (via Saturn AV connector)
  • Seamless Switching: automatic, no sync loss between 240p/480i and 288p/576i

Performance Notes

  • Composite and S-Video are fully supported on the GBSC Pro hardware, but users report they can look darker or lower quality compared to RGB or component.
  • RGB SCART and YPbPr remain the recommended inputs for the sharpest, most stable picture.
  • Built-in Wi-Fi and firmware updates allow for scanline settings, profiles, and easy adjustment.

Description

The GBSC Pro (GBS Control Pro) is a retro video scaler/upscaler built to make classic consoles look their best on modern TVs and monitors. Plug in SCART (RGBS), Component/YPbPr, S‑Video, Composite, or VGA, and the GBSC Pro converts your analogue signals to crisp digital video at 720p/960p/1024p/1080p with low‑latency, real‑time processing—so your inputs stay responsive and your 8‑bit to 128‑bit libraries shine without the blur, noise, or lag you get from basic adapters.

Dial in the image exactly how you like it using built‑in scanlines for 240p/288p sources plus RGB/ADC gain, linear filtering, and sharpening for a clean, authentic look. Control is effortless: tweak settings from the OLED display and front‑panel knob, navigate the on‑screen display via the IR remote, or jump into the Wi‑Fi web UI to save and load profiles per console so your favourite presets are always one click away. Manual input selection keeps switching sources fast and frustration‑free.

With broad PAL & NTSC compatibility, GBSC Pro is a perfect match for systems like SNES/Super Famicom, Mega Drive/Genesis (incl. 32X), Saturn, PlayStation/PS2, Dreamcast (VGA), GameCube, Wii (Component), Neo‑Geo AES, original Xbox, and pre‑HDMI Xbox 360, plus 15 kHz JAMMA arcade boards via RGBS.

Note: Wii composite is not supported (use Component, NTSC S‑Video is fine);

Atari 2600/800 and Commodore 64 are not supported.

Package Includes

  • 1 x GBSC Pro Upscaler
  • 1 x Instruction Manual
