Long Island Retro 2026 was a good opportunity to polish up the Multi-Screen Nintendo 64 setup I built a few years back.

The system takes four-player split-screen games and separates each player's view onto an individual display. At events, we use a fifth screen to show the original full-screen output, which helps illustrate what the system is doing and makes navigating menus easier.

The main build uses an original Nintendo 64 with an UltraHDMI upgrade. The setup also works with an EON Super 64 and newer systems like the Analogue 3D and M64, but UltraHDMI gives me the ability to adjust the overscan for each output.

That adjustment is useful because a few games, like Superman 64, handle their four-player output a little differently and require some additional fine-tuning.

It was nice to dust off this project and give it a little extra polish with things like a custom jewel, printed details, and some other finishing touches.

Wireless lightgun's on the SuperStation (and misters) for all cores!
