Xbox One emulators
The Xbox One is an eighth-generation console produced by Microsoft in 2013. Early in its life, it was heavily criticised for intrusive DRM, such as always-online and lack of used game sharing. These have since been removed. Notably, this console runs on the x86 architecture, so it is essentially a PC.
Despite this console using on the same architecture as PCs it is not easy to emulate. This is due to being such a complex architecture  and using undocumented hardware. Xbox, which also runs on x86 has similar problems.
