Embrace classic multiplayer gaming on Sega Saturn with JoEngine’s new Serial Link cable support for seamless network play.
If you’ve ever dreamed of linking your Sega Saturn consoles for some old-school multiplayer magic, now’s your chance. The open-source JoEngine has just taken a giant leap by adding support for the Serial Link cable, breathing fresh life into multiplayer experiences over the network.
Bringing Sega Saturn Multiplayer Back to Life
The passionate developer Slinga spent several weeks this past early autumn crafting a demo that leverages the Saturn’s serial port to send data between consoles—or between a console and a PC running an emulator. This nifty proof of concept didn’t just sit on the shelf; Slinga shared the demo along with its source code with the JoEngine development team. The idea caught fire, and they’ve already baked this feature into JoEngine’s SDK.

A Look Back at Slinga’s Homebrew Innovations
Fans of Saturn homebrew might recognize Slinga from his previous exploits. About five years ago, he created the Save Game Copier, an ingenious utility that transfers save files between Saturn’s internal memory, cartridges, disc drives, and even devices like Action Replay and Satiator. This kind of dedication to Saturn preservation and enhancement perfectly sets the stage for his latest Serial Link contribution.

What’s the Serial Link Cable Anyway?
The Serial Link cable, also known as the Taisen Cable, was a Japan-exclusive accessory, notoriously rare and only supported by a handful of Saturn titles. Slinga’s demo has been tested on both Japanese and American Saturn consoles, plus PCs, but he’s a bit on the fence about its reliability with PAL-region machines. Those differences in hardware quirks might still throw a wrench in the works.

DIY Meets Retro Tech: The Custom Saturn-to-PC Cable
To test the data transmission between Saturn and PC, Slinga used a hand-crafted cable sent by another homebrew devotee, the creator of the game Knight0fDragon. On one end, a USB connector plugs into the PC, while the other end fits snugly into the Saturn console. It’s a perfect example of the homebrew community’s spirit—building bridges between classic consoles and modern machines.
