ModRetro M64: AMD Artix UltraScale+ FPGA Powers a 4K-Ready N64

The ModRetro M64 FPGA Nintendo 64-compatible console is the kind of hardware that makes a specs-obsessed editor sit up straight. Detailed by CNX Software on June 3, 2026, and built in collaboration with AMD, the M64 ditches software emulation entirely and rebuilds the Nintendo 64 in reconfigurable silicon. The result is a fanless, $199 machine that takes your original cartridges and controllers, then upscales the whole thing to 4K over HDMI. Let me walk you through the numbers, because this one earns the geek-out.

Hardware-Level Emulation on an AMD Artix UltraScale+ FPGA

The headline component is an AMD Artix UltraScale+ FPGA. Instead of running an N64 emulator on a general-purpose CPU, ModRetro programs the FPGA's logic fabric to behave like the original console's chips at the gate level. That distinction matters: hardware-level emulation reproduces the actual timing of the system, which translates to better accuracy and lower input latency than a software stack juggling a guest CPU on a host OS.

The M64's FPGA core builds on the open-source N64 MiSTer core developed by Robert Peip, a project that has earned a serious reputation in the FPGA preservation scene. ModRetro has pledged to share its improved core code with the community after launch, so the work feeds back into the ecosystem it borrowed from. For an open-source N64 console, that round-trip is the whole point.

PSRAM Architecture and Overclocking Headroom

Here is the spec that separates the M64 from rival FPGA consoles: its PSRAM-based memory architecture. According to CNX Software, this design gives the M64 extra overclocking headroom compared to competing FPGA hardware. In practical terms, that bandwidth ceiling is what lets a cycle-accurate core push past the N64's stock clocks for smoother frame pacing without breaking compatibility. Pair that with a fanless thermal design, and you get silent operation with thermal margin to spare.

Modern Connectivity, Original Cartridges

The M64 threads the needle between authenticity and 2026 convenience. It accepts genuine N64 cartridges and original controllers, so your shelf of physical games still matters. On the output side, you get HDMI with 4K upscaling, plus WiFi, Bluetooth, and USB-C. Wireless over-the-air updates mean the core can keep improving after the box ships, and a 5-second boot-to-game is a refreshing number after years of menu-laden retro hardware.

The Trident Pro Controller

ModRetro also redesigned the input. The new Trident Pro Controller uses a drift-resistant TMR (tunneling magnetoresistance) magnetic joystick, a sensing technology that avoids the wearing contact surfaces responsible for stick drift. For a controller meant to outlast the games it plays, magnetic sensing is exactly the right engineering call.

Pricing and Launch Details

Here is how the M64 lands. The price is $199 for early adopters, with one Trident Pro Controller in the box. Launch is set for July 27/28, 2026, with AMD spotlighting the partnership on its own blog. For context, that puts an Artix UltraScale+ FPGA, a TMR controller, and 4K output under the cost of many modern game pads bundled three to a box.

What I appreciate most as a hardware writer is the philosophy: take a proven open-source core, give it a serious memory subsystem and headroom, and commit to handing improvements back to the community. The M64 isn't just a nostalgia machine. It's a well-specced piece of FPGA engineering that treats preservation as a benchmarkable discipline. Mark July on the calendar; I'll have the latency numbers when it ships.
