Zesty is a pin-accurate, cycle-accurate NES/Famicom emulator written in Zig.
As Zesty is still heavily work-in-progress, it probably won't work for your favorite games just yet — although I'm currently hard at work making that happen.
Zesty's canonical repository is hosted on Tangled, although a mirror is also available on GitHub. Issues and pull requests are welcome on both forges, though contributing on Tangled would be more preferrable - thanks!
