puNES is an open-source (GPLv2), Famicom (NES) and Famicom Disk System (FDS) emulator. It is noted for its high accuracy in tests.

As of April 2026, development of the current branch is currently stalled, as the developer is rewriting the emulator from scratch.

Overview

puNES is ranked as the second most accurate NES/FDS emulator behind Mesen, with a score of 98.08%.. However, these test ROMs, unfortunately, don't test everything that matters for accurate emulation (and in some cases, test stuff that doesn't matter for emulating any games). So the test results may be a bit misleading, but that does not mean it is not a high accuracy emulator.

Like many other Famicom emulators (such as Nestopia), it has cycle-accurate CPU emulation.

In addition to its high accuracy, puNES also has some nice, standard emu options, including a good input configuration UI and rewind functionality.
