It is ranked Like many other Famicom emulators (such as the most [[Nestopia]]), it has [[Emulation Accuracy#Cycle accurate NES emulator, with a score of 96.2%.<ref>http://tasvideos.org/EmulatorResources/NESAccuracyTests.html</ref>. However these test ROMs, unfortunately, don't test everything that matters for |cycle-accurate ]] CPU 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 [[Emulation Accuracy|cycle-accurate]] CPU emulation.  In addition to its high accuracy, puNES also has some very nice, standard emu options, including a very good input configuration UIand rewind functionality.
