How do I know if I have a 20 or 21 pin Console?

20 pin drives are motherboard revisions VA0, VA0.5, VA0.8, VA1.
Please note some VA1 revisions come with a 21 pin drive instead of a 20 pin drive.
In order to find out if your console has a 20 pin drive without opening it, you can look for a screw at the back, next to the power supply socket.
If you see 3 screws, then it’s a 20 pin VA0. If not, then you need to check that the power and reset buttons are oval in shape and not round.
Another way to check, is to open the CD lid and look towards the back of the cd mechanism, to the gap on its right side.
If you see a white ribbon cable running towards the back, then you have a 20 pin drive.
If none of the above helps, then you most likely have a VA1 console and you need to open it to make sure your drive uses a 20 pin ribbon.


How to update the firmware

Updating your Fenrir Duo's board’s Firmware, is incredibly easy.Tools Required: 

  • A microSD card, FAT32 formatted
  • A computer (Windows, OS X or Linux) with a microSD or SD card slot with adapter

4. Safely eject the card.

5. Make sure your Sega Saturn is turned off. Insert your microSD card to the Fenrir Duo microSD card slot.

    Best ODE for Saturn

    Posted by Tim Williams on Apr 18th 2024

    There were a lot of options for Saturn ODE`s and I don`t regret going with the Fenrir. It`s among the most supported and actively developed option, and is reasonably priced. It`s a cinch to install, supporting all Saturn models and including both ribbons. I purchased the 3D printed bracket to keep it clean. While some other ODE`s offer an option to keep the disc drive, consider that Saturn optical drives are incredibly unreliable and will inevitably break or stop reading discs, and they already have trouble reading CD-R`s. With the Fenrir it`s kind of irrelevant anyway - you won`t miss discs. It`s incredibly easy to make images/ISO`s of your discs and put them on the SD card. And while some other ODE`s offer faster load times, that itself causes an inaccurate experience: since fenrir goes over the optical drive bus it is 100% accurate.

    I friend of mine have this Item & it worked like a charm, the Installation was Very Simple, I Installed it for my friend and I helped him add the Games on the 128gb SD Card, it’s very simple and it’s fun when you don’t have to worry about using the cd drive anymore because the cd drive dies eventually & I Strongly Recommend this Item to Anybody that’s deep into gaming.

    Easy Install, Easy To Setup

    Posted by JuanGrande386 on Feb 15th 2024

    One of the easiest ODEs to install. Just remove a screw from from underneath the Saturn disc drive and remove the power/ribbon cable. Take the drive out and set this ODE right on the brackets. Pop in your SD card and you should be good to go.
