The Retro GEM is the ultimate HDMI kit for your retro gaming consoles.
- Digital lag-free HDMI output
- Simple firmware update procedure via WiFi
- Advanced scaling and video filters in Shiny Edition
- Native Direct video in Basic Edition. Perfect for people who already own an external scaler.
This kit can be installed into all console variants except motherboards with the anvil IC. These are later model variants that no longer expose the digital bus.
The HDMI output setup :
- no cut -> sacrifice rf port (mini hdmi)
If upgrading an existing 3DO RGB mod or like installation you will need to undo any tracecuts or resistor lifts that were performed.
The optional spare flex isn't required and is already included in the console kit. But sometimes mishaps happen during the install and an extra flex will give you a second attempt.
The Retro GEM must be soldered into your gaming console. These modifications are advanced and require a high level of soldering skill. Never soldered before, do not fret! We have recommended installers that can do the modification for you. You can see our full list of installers at the bottom of the details page.
The basic can be upgraded to the Shiny at any time, even after installing into a console. Upgrades can be purchased here or through the GEM kits on screen display.
3DO Open OSD:
- L Trigger + R Trigger + DPad Right + X
