I like to mod consoles, and this time around I wanted to build a cool Sega Saturn with some modern features. I like the whole concept of ODEs (Optical Drive Emulators), but since there are some theoretical limitations to each one of these, I went with a dual ODE build. This way, there would be a backup solution to run a game if one of the ODEs should have compatibility issues with a specific title.
When choosing the Saturn variant for the build, I first looked at the JAP Model 1. I really like the looks and color scheme of the unit, but there are some drawbacks in my opinion. The early Model 1s are built a lot differently from the later models, meaning the PSU is top-mounted, the shielding is thinner, and the poles for the CD drive are built right on top of the motherboard, rather than being attached to the shielding. There are also more cables and daughterboards, which make the internal look a lot messier compared to later models. Besides that, the power consumption is a bit higher (15 W compared to 12 W), and the access light would suddenly serve no purpose.
I instead went with a JAP Model 2. This version has, in my opinion, a more streamlined internal build and feels more sturdy. Things that I really appreciate when finding a good base for a mod. Besides that, a lower power consumption is always great, both for the electric bill and lower temperatures.
One of the first things that I had to do was to replace the original power supply. This is because the console is a JAP model, which runs on 110V. That would not work with the 230V that is the standard where I'm from, and I would have damaged the system if I had tried. Instead of using a step-down converter, I removed the original power supply and installed a SaturnPSU, which I bought from AliExpress. I have 3 of these SaturnPSUs, and until now I have had no issues with them. They remove some heat generation from the Saturn, clear up some internal space, and move the power brick outside the console itself. The SaturnPSU is easy to install and compatible with all the Saturn variants.
Even though there are only 2 major Saturn models, there are several revisions regarding the internal build of the console. As far as i know, there are 15 versions of the motherboard, which again has resulted in some different designs of the internal shielding. In most cases - besides the first version with the top-mounted PSU - the power supply is attached to the top metal shielding with a screw.
In this build, which is built from a JAP Model 2 - VA6, the SaturnPSU can be attached with the same screw as the original PSU. It only requires some minor bending of the part of the shielding where the screw is placed.
With the SaturnPSU installed, I went on to install the Fenrir Duo ODE. First, I 3D printed a mount for the Fenrir. There is a greatmodular design that can be downloaded for free, which looks awesome, is well made, and is easy to print. I did some filament swapping along the way to achieve a clear black/white color scheme on the top, making the Fenrir logo stand out. To do this, I simply excluded the logo part of the build from the support feature (in the slicer program) and manually changed the filament after the first ~10 layers had been printed. I also bought a microSD extender cable that makes it possible to insert one end into the Fenrir and glue the other end to the top part for a cleaner overall finish. Besides looking more complete, this method also makes it so much easier to insert/remove the micro SD card because it's much more accessible.
I bought the Fenrir Duo ODE from AliExpress, which means that there is a very big risk that the Fenrir is a clone and not an original Fenrir. When it comes to ODEs and clones of these, there tend to be a lot of opinions around the internet regarding this matter. Many people argue that you should buy the original unit to support the developer, and I totally get that. The reason why I personally don't care that much about this moral argument is because the main appeal of ODEs is to enable piracy. I would argue that ODEs in most cases are bought and used as a tool to play games that you don't own (piracy), wherefore I find it strange to be upset about someone pirating your pirate tool. But yeah, that's just my opinion. As far as I know, some years ago the Fenrir developer put out a firmware update that spots clones and makes these units behave strangely. If you have an original Fenrir, all is good. If you have a Fenrir Duo clone, it is important to download the correct firmware. Both firmwares have the same version number, 1.5.8, but the file size is different. The size of the "clone friendly" version is 494 kb, whereas the newer version (that messes with the clone) is 498 kb in size.
Like most of the things used in this project, the Saroo that I use also came from AliExpress. Where the Fenrir is installed internally and physically replaces the CD-ROM drive, the Saroo instead uses the expansion port in the top/back of the Saturn. This is the same port that can be used for memory cards and RAM expansion cards. One of the cool things about the Saroo is that, besides being an ODE with almost 100 percent compatibility for the entire game library, it also serves as a RAM expansion and memory card. This means that it is possible to run games from the Fenrir that use the Saroo as a 4 MB RAM expansion. That said, I would assume that there could be some compatibility issues regarding using both the Fenrir and Saroo in tandem, but nothing that couldn't be fixed over time with a firmware update.
Over the years, there have been some issues with different kinds of 3rd-party cards for the expansion port. Mainly because some of these either used a PCB that was too thick and/or because the edge of the connector wasn't beveled. This led to damaged expansion ports, but luckily the Saroo has a nice beveled connector and fits perfectly.
The Saroo is easy to set up and use and has some nice features when it comes to uploading custom backgrounds and music. Because of the boot order of the Saturn, the Saroo boots up before the Fenrir. When wanting to use Fenrir, it is very fast to switch over by using the “Load Game Disc” function in the Saroo main menu.
I really do like the original Sega Saturn controllers for the JAP models, and since I wanted to have this Saturn standing on a shelf above the TV, I thought that it would be smart to have a wireless solution before I would pull the cord and drag the Saturn off the shelf. Luckily, Retro-Bit offers a nice controller, that is wireless and has the same layout as the JAP controller. Furthermore, it has dual analog sticks. Overall, a great controller!
At this point the Saturn had no CD drive, which means no mechanical moving parts. Therefore, it would be perfectly fine to place it in a vertical position. I did actually test the Saturn in this position with the CD drive, and it worked fine, but I can't say how and if it would damage the CD drive over time, since the Saturn was originally designed to lie flat.
With a desire to showcase my Saturn in a vertical position, I had to find a solution for a stand. After looking it up, I couldn't find what I was looking for, and because of that, I ended up designing my own Sega Saturn Vertical Stand, which takes inspiration from the PlayStation 2 vertical stand. This design is compatible with both the model 1 and 2 Sega Saturn, and the .STLcan be downloaded for free.
The last finish for this Saturn project was to cover up the worn and scratched case with some Batsugun-inspired art.
