Turbo Duo / PCE Duo Turbonanza Install

The Turbonanza is an internal mod board that replaces the stock DIN and adds a Sega Saturn-style DIN connector, unlocking RGB, color-accurate S-Video, and composite video output — all from a single port. Using widely available Sega Saturn cables, you can connect your console to a scaler like the RetroTINK or OSSC, or get a stunning picture directly on a CRT.

Compatible with: Turbo Duo, PCE Duo, and Duo R/RX.

⚠️ Recap Requirement: The Turbo Duo and PCE Duo are notorious for capacitor failure, and failing capacitors can cause damage shortly after installation. Captain Retro will not install a Turbonanza on a Duo system that has not been recapped. If your console has not already been recapped, please add our Recap Service to your order or select it during checkout. By selecting the "Capacitors have already been recently replaced" option, you are confirming that the original capacitors have been replaced prior to sending your console in.

The mod board required for this service is not included in the base price. You may source the board yourself or we can source it for you. Pricing reflects the selected option.

This is a send-in service. No payment is collected at checkout — you will receive shipping instructions and invoice details via email within 1-2 business days. All consoles must be tested and confirmed in full working order prior to shipping. See our Shipping & Send-In Instructions page for details.
