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.
