The z386 project reproduces Intel’s 80386 CPU on FPGA by executing the original microcode, achieving about 70 MHz i386-equivalent with paging and protected mode support on boards like Cyclone V and Gowin GW5A, prioritizing archaeological fidelity of the original hardware over peak performance and enabling classic software such as DOOM.
Time Extension’s Damien McFerran reviews the $210 SuperStation One, a PS1‑shaped FPGA box that blends MiSTer FPGA cores with PS1 accessory and media support via SNAC, plus built‑in Bluetooth, Wi‑Fi, NFC, and a wide array of legacy AV outputs. With Console Mode in development and a forthcoming SuperDock for optical media, it promises a highly authentic, low‑latency retro PS1 experience and broader MiSTer functionality, though it runs warm and currently exists as a standalone system rather than a seamless MiSTer extension.
Commodore issued a firmware update for the C64 Ultimate FPGA and explained it will not support or allow third-party patches, to protect hardware, warranties, and support costs. The update adds USB mouse support, improves the BASIC editor, and introduces a music-detect mode; Commodore says firmware built for non-official boards could cause issues and will be blocked or restricted, though the company is evaluating paths that balance user freedom with protection and is inviting feedback.
Sergiy 'srg320' Dvodnenko says the MiSTer 3DO core likely can’t reach 100% accuracy because VRAM emulation needs more internal FPGA memory and several details of the Sprite Engine (and its DMA) remain unclear; while the core isn’t resource-heavy, full fidelity may be unachievable, though future reverse-engineering of MADAM/CLIO chips could improve things and a highly playable core may still satisfy retro gamers.
Francisco Ayala Le Brun has recreated the 3DFX Voodoo 1 GPU in SpinalHDL for FPGAs, detailing the fixed-function hardware architecture and the timing/bug challenges of mapping a classic GPU onto modern programmable logic, with a GitHub repository for curious readers; the piece nods to Nvidia’s late-90s acquisition of 3DFX and notes the option of upgrading real Voodoo memory for those who own original hardware.
A hobbyist has built an FPGA-based system that emulates a 486 PC, capable of running vintage OS and games like Linux 2.2.6, MS-DOS, DOOM, and Wolfenstein 3D, using a Xilinx Spartan II FPGA and a vintage i486 CPU, showcasing a remarkable DIY retrocomputing project.
The Analogue Pocket now supports an app called MROM that allows users to dump ROMs and save data from physical Game Boy cartridges to preserve their collections, although the feature is still in early development and may have limitations.
Recent research and expert analysis suggest that the Analogue 3D, a device designed to emulate N64 cartridges on modern TVs, may not be entirely cycle accurate to the original hardware, despite claims of 100% accuracy. While still highly regarded and playable, the device's FPGA implementation has minor discrepancies, though a fix is reportedly in development. The device remains a significant improvement over emulators, but its precision may improve with future updates.
The Commodore 64 Ultimate is a highly faithful FPGA-based recreation of the classic 1982 home computer, offering modern features like HDMI output, USB, Ethernet, and compatibility with original peripherals, while maintaining authentic performance and sound. Despite some build quality concerns and a high price, it is a compelling device for enthusiasts seeking an authentic and upgradeable C64 experience.
The Commodore 64 Ultimate is a highly authentic FPGA-based remake of the classic C64, offering modern features like HDMI output and full compatibility with original games and peripherals, making it a top choice for enthusiasts despite its high price. It revives the '80s microcomputer experience with modern enhancements, appealing to dedicated fans and potentially sparking a microcomputer revival in 2025.
Sergiy Dvodnenko, creator of the Saturn FPGA core for MiSTer, refutes claims that his core is '100% hardware accurate,' stating it is still far from complete accuracy, despite passing emulation tests and providing a near-authentic gaming experience.
Analogue has shown its FPGA-based N64 console, the Analogue 3D, running for the first time, with footage of it playing 1080 Snowboarding. The console, expected to launch in Q4 2024, features a controller from 8BitDo and faces potential competition from the ModRetro M64 upon release.
Commodore International, under new ownership, has announced the Commodore 64 Ultimate Edition, a modern recreation of the classic computer powered by an AMD Xilinx FPGA, with pre-orders available for three editions, expected to ship in late 2025, featuring high compatibility with original games and peripherals.
The ModRetro Chromatic is a new Game Boy Color clone that uses FPGA technology to run physical cartridges, offering a modern take on the classic handheld. Priced at $199, it features a magnesium alloy shell, a sunlight-readable backlit display, and compatibility with Game Boy and Game Boy Color games and accessories. While it lacks some features of its competitor, the Analogue Pocket, such as save states and broader cartridge compatibility, it provides an authentic gaming experience with a focus on nostalgia. The Chromatic is aimed at fans of the original Game Boy, offering a faithful recreation with modern enhancements.
Palmer Luckey, founder of Oculus, is launching the ModRetro Chromatic, a $199 FPGA-based Game Boy system. This device features a pixel-perfect IPS display, link cable port, USB-C charging, and support for original Game Boy and Game Boy Color cartridges. Set to release in holiday 2024, it aims to be a high-quality tribute to the original Game Boy, available online and at GameStop.
