Switch emulation is still in its infancy and, like most emulation, requires a machine capable of playing it. The requirements are high, but most modern gaming PCs with dedicated graphic cards should have enough juice to emulate Switch HD content.

Before that, a word on piracy. Emulation should never be used to pirate content meant for the Switch. It can be used to emulate games you already have but want to play on the PC instead of the switch. Also, searching for pirated Switch games turns up results that may take you to files that contain malware, so think about your data and computer before deciding to go the piracy route.
