Because disc drives are for chumps!Features:- Supports from VA1 to VA5 Motherboards.
- No trimming required and minimal soldering.
- Supports every major Saturn ODE.
- USB-C for power.
- Less than half the size of a stock Sega Saturn.
- Sliding expansion port door for easy access.
- Low cost BOM.
- Pre-supported STL files for easy printing.
**************************
BOM: Sega Saturn SV+Mini BOM (Mini coming Soon)**************************
Printing:Attached are STL's for both FDM and SLA printing. The FDM files are pre-supported for easy printing. It is recommended to print at the specified layer heights so that the built-in supports function as intended.
Certain smaller parts that are pre-supported may need a little assistance from a blade to break free from the support. Buttons may need to be sanded at the bottom
**************************
Supported ODE's:Fenrir Duo: Mount points are on the top shell and the included FFC will reach. The power cable will need to be made longer and soldered to a nearby 5v pad. Example:
Saroo: Without an optical drive connected the system will be missing the audio clock. For audio to work correctly you will need to install an 8.388Mhz oscillator (BOM).
The location of this clock line varies if you have a 20 pin or 21 pin drive model. Picture provided shows where this clock line can be located:
Satiator: With the latest update it's plug-and-play (should be).
**************************
Powering the unit:At an absolute minimum you will need a 3v or 3.3v regulator (either is fine). You can power the Saturn directly from the USB-C 5v, this will also be used to power the 3v regulator. However, powering the system this way can lead to minor noise in the video signal if you have poor quality AV cables or a poor quality USB power supply. Results may vary.
It is recommended you use both a 5v and 3v reg to power the unit as this can lead to a cleaner video signal, in this case the USB-C power input can be set to 9v to power the regs. See the BOM for regulator options.
**************************
Assembly:It is highly recommended that you perform the FRAM mod before doing anything, this will ensure that your saves are stored even when the internal battery dies. This is not required however.
Step 1: Remove the CD lid switch and PSU prongs as they are too tall for the case, how you do this is up to you.
Step 2: Use a small dab of hot glue to mount the bistable switch to the printed bistable switch mount. Wire up the USB-C input to the bistable switch appropriately and the switch outputs to the Saturn/regulators. Power up the Saturn to make sure it is functioning correctly.
Step 3: If everything is working correctly then install the Saturn into the shell, make sure you have inserted the longer controller FFC as you won't be able to do this with the controller board mounted. Use appropriate length screws from the disassembled saturn (if they are too long don't worry, they won't bottom out and damage the case). Mount the Controller board above the mainboard and connect the FFC.
Step 4,5,6,7,etc: The rest of the build is pretty self explanatory. You're a clever cookie, I'm sure you'll figure it out
Final things to note: - The reset button mechanism can be a little finicky, sand parts of the button and mechanism unit it feels decent.
- Use the BLACK case screws from the Saturn to screw the top and bottom of the SV together, the guides and mounts have been made specific lengths for them so they don't bottom out and damage the top shell.
- Probably some other things I've missed.
Thanks to:
@Y2K for assistance in helping locate the audio clock lines initially.
@YveltalGriffin for moral support while pulling my hair out over the noisy video issue.
