Nestopia UE is a Famicom (NES) and Famicom Disk System (FDS) emulator. Nestopia allows graphical enhancements such as texture scaling and TV filters, as well as netplay support. It's one of the most popular and most compatible emulators around.
According to TASVideos, Nestopia is ranked as the fifth most accurate Famicom emulator, with 1.40 scoring a score of 82.3%. Other NES emulators, such as Mesen and PuNES, have higher scores on these tests. However, these test ROMs 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, it has cycle-accurate CPU emulation.
