• MiSTer FPGA A/V Pro v9.2
• MiSTer Multisystem
• MiSTer Pi (Clone)
• MiSTer QMTech (Clone)
• MiSTer Jammix FPGA
• xtremeMiSTer
• Analogue FPGA with DAC
• Analogue FPGA with Analogizer
• ZX Spectrum Next (KS1/2/3) / N-GO

✅ Specifications:

• Connector A: 15-pin D-sub (MiSTer VGA video output)
• Connector B: EuroSCART (CRT TV video input
• Connector C: 3.5mm stereo jack (MiSTer audio input)
• Cable Length: 1.6 meters (default)
• Color: Black
• Sync Signal: VGA pin 13 is connected to SCART pin 20 through a 470Ω resistor
• RGB Switching: VGA pin 14 is connected directly to SCART pin 16 (1.6V or less, no attenuation required)
• Compatibility: Works with MiSTer I/O board set to either default or 5V configuration

⚙️ Configuration for MiSTer FPGA:

To enable 15 kHz RGB output via SCART, you need to update the mister.ini configuration file.

We strongly recommend backing up your existing 📄 mister.ini before applying this changes:

• forced_scandoubler = 0
• composite_sync = 1
• vga_scaler = 0
• direct_video = 0 *

* This option should be set to 1 (enabled) only when using HDMI-to-VGA DAC dongles with Direct Video. If enabled without a DAC, it may result in incorrect colors.

Note: The Scandoubler setting in the OSD menu (accessed with F12) should be set to OFF for all cores.

⚙️ Configuration for Analogue DAC:

• When using this cable with the Analogue DAC, please ensure that the firmware is up to date and that “RGB Composite Sync” is enabled in the Advanced Settings.

⚙️ Configuration for ZX Spectrum NEXT / N-GO

• When using this cable with the ZX Spectrum NEXT, stay pressing key “R” during the boot to set the 15 kHz RGB mode.
