Analogue recently announced the Analogue 3D, an FPGA replication of the N64 home console that will allow users to run their existing carts and controllers on a system which offers incredible accuracy for non-original hardware.
However, if you're a long-time follower of the site, you'll be aware that there have been some pretty exciting developments in this area already, with an N64 FPGA core already in active development for the MiSTer platform.
The ever-reliable Modern Vintage Gamer has produced a video which showcases just how far this core has come in a surprisingly short space of time. Developer Robert Peip (FPGAzumSpass) has been solving many issues relating to the core over the past month or so, and, while it's still very much a work in progress, the finish line is in sight.
While N64 on MiSTer naturally won't allow you to use your cartridges, it should provide just as faithful an experience once the core is finished.
