N64 Splitscreen Arcade Table

Description

I'm trying to build a Custom N64 Arcade table with 4 screens and the option to switch between fullscreen an 4 player splitscreen (each of the 4 screens shows only the coresponding part of the Splitscreen) The Controller is also custom design: Two sticks, the left one for normal play, the right one (with better handle, and 4 buttons, ABZR) for games like starfox64. I will post updates on design an Hardware choices and links to used githubs and Thingiverse files in further updates in case someone wants to rebuild this... For further information see my blog (german) linked below. Work in Progress.

Components

1 × Nintendo 64

4 × Pi pico for Usb2N64 Controller

4 × rp2040 with 4 analog inputs (the official pi pico has only 2 analog inputs)

4 × Ikea Lack shelf 30x26x5cm Housing for the 4 arcade controllers

Just a little Photo Update.
Minor Update
florian.bednarz • 06/24/2026 at 09:47 • 0 comments

Minor Update:
1 Controller done

2 Controller half done (playable, but "flightstick" missing")

2 stacked ikea lack tables as base

hdmi mod for the n64

the 4 controllers are removable for transport (the case for the controllers are just ikea lack shelfs)

first test of corner fittings and plots for the table.
Small Update

Some small Update:
- Changed the screens to some used 15.6 '' Notebook screens => not so heavy
- rs232 for the Matrix Controller works now with some esp8266 (wemos D1) => you can switch between 3 Modes:
1. every screen shows fullscreen
2. every screen shows 1/4 of the screen (4 player split)
3. screen 1 and 2 show half (top-botton) of the screen, 3 and 4 fullscreen (2 Player horizontal split)
- one prototype controller is done
- updated design (with some Ikea furniture) to make the build easy an portable
More Updates will come when the 4 Controllers are done and i need to install a hdmi mod to my N64, because the Signal is to Blurry (N64=>AV2HDMI=>Matrix Controller(input and output 1080p)=>old Notebook screen 1366x768) => the av or s-video output from the n64 is to blurry to come up with all this scaling...

New Parts arived:

N64 Extension Cords and 4rp2040 pro micro

I flashed the pi picos with https://github.com/pdaxrom/usb2n64-adapter and tested everything on the real thing. Works like a charm.

Next step will be the N64 AV to hdmi converter to use the Video output of the N64 with the 2x2 Matrix controller.

Thanks for your input!

I go the easy run for the first Version:

I plan to use only 4 player and 4 player Splitscreen games. Therefore i have a 2x2 matrix Controller connected to the Output of the N64. This Controller can show the whole screen on all 4 displays, or 1/4 of the screen on each coresponding display. So you can play N64 multiplayer games in Splitscreen and each player just sees their 1/4 of the screen in fullscreen on his display.

No custom roms, FPGAs etc involved (which is to complicated for me now ;-) )

Crts was also an idea, but as you mentioned it would be very heavy an much bigger...

Yeah, I never owned an N64 so i didn't cross my mind that this is for 4 player game modes. It's never too late to make something like this though. Shared memory busses for each game instance would be difficult to implement but it can still be done no doubt. It's only within a matter of how much you can fabricate yourself and how possible it is to find the right ICs for the task.

You'll probably need a custom board to make this work properly. You can make a variant of an N64's motherboard using the same components along with 4 ports supporting up to 4 different ROMs. If you actually build this out, it also probably means that you may have to use an FPGA to simulate 4 different instances of the same system running a different game. Perhaps you'd have to make your own toolchain for handling ROM data as well. Maybe you can run a cluster of CRTs instead of LED screens and include speakers at the top of the screen windows for that classic feel. The cabin would also have to be a bit larger in order to do that and would need to support the weight of all four CRTs at the center while also being a bit stylish to better appeal to the players. You could also incorporate some aspect of the classic JAMMA standards too with fully functional coin slots at the bottom but that'd probably mean that you'd have to start writing some custom state control logic. Overall, it's a very cool project and I'd like to make a version 2 of this.
