ModRetro has announced the M64, an open-source Nintendo 64-compatible console powered by an AMD Artix UltraScale+ FPGA, designed to play original cartridges using hardware-level emulation instead of software.
The M64’s reliance on an AMD Artix FPGA enables accurate and responsive gameplay, and the console supports original game cartridges and controllers, while also adding modern connectivity features such as HDMI, WiFi, Bluetooth, and USB-C.
ModRetro M64 specifications:
- FPGA – AMD Artix UltraScale+ (16nm architecture)
- Memory – PSRAM
- Storage – MicroSD card slot (for firmware updates and potential homebrew applications)
- Media Interfaces – Dedicated Nintendo 64 physical cartridge slot for original retro media preservation and play.
- Display – HDMI port (upscaling for modern TVs, supporting custom video filters like Scan Line and CRT profiles)
- Audio – Digital audio output via HDMI
- Connectivity
- Bluetooth with advanced “SCI” wireless mode (ModRetro’s own low-latency protocol)
- Wi-Fi support for firmware upgrade
- USB – 3x USB-C ports for power, accessories, and controllers
- Expansion – 4x front-facing Nintendo 64 controller ports supporting original wired controllers, accessories like Rumble/Transfer Paks, and modern third-party add-ons
- Misc
- Power Button
- Menu Dial
- Eject Button for cartridges
- LED lighting for console port and cartridges
- Compatible with original N64 controllers, NSO N64 controllers, 8BitDo gamepads, and the included M64 Pro controller
- Power – Dedicated USB-C port on the back specifically for power
- Dimensions – TBD
- Enclosure – Translucent shell without adhesives (designed for easy repairability)
ModRetro mentions that they use four fast PSRAM chips instead of DDR memory to get more consistent, low-latency performance, which is important for accurate N64 emulation, even though DDR can be faster in peak speed. The company is also developing a CRT AV adapter that will automatically detect 240p/480i signals and output composite, component, and S-Video for use with vintage CRT monitors.
The company also offers the M64 Pro Controller, which takes on the classic N64 “Trident” design and connects via Bluetooth or wired USB. The company also upgraded the joystick with a modern TMR (Thumbstick Magnetic Resonance) analog one to solve the drifting issues of the original N64 gamepad. It also features a ceramic-coated aluminum backshell and swap-in AA or rechargeable battery options.
The core logic running on the AMD FPGA is built upon the open-source N64 MiSTer core, originally developed by Robert Peip (FPGAzumSpass). According to ModRetro CEO Torin Herndon, the company is actively adapting and improving this code to fully utilize the faster fabric and 6-input LUT architecture of the AMD UltraScale+ platform. The company has promised to share its improved FPGA core code with the community after launch to help improve accuracy and preserve the original hardware.
Previously, we have written about FPGA-based retro gaming consoles, including the SuperStation ONE home console built around an Intel Cyclone V SoC, and the Roshambo Retro Gaming Console DIY Kit based on the Rock64 or RockPro64 Board. We have also written about handhelds like the open-source Game Bub handheld, which relies on an AMD Xilinx Artix-7 chip to interface with original Nintendo cartridges.
The ModRetro M64 will launch on July 28, 2026, priced at $229.99 with one controller included, while extra controllers cost $89.99. Alongside the console, ModRetro will also release new indie games on physical N64 cartridges, including Xeno Crisis, Extreme-G: Turbo Fusion, and Buck Bumble.
