So, in summary, we can talk about three types of cycle emulation: "partial cycle-accuracy", "cycle-based accuracy" and "full cycle-accuracy". These can be considered as subsets of "cycle accuracy." Due to technical challenges and performance considerations, emulators often employ either "partial cycle-accuracy" or "cycle-based accuracy" depending on the specific requirements.
Mesen, CEN64, BlastEm, NanoBoyAdvance, Azayaka, MartyPC and Stella are recognized for their cycle-accurate emulation, though for knowing the specific degree of cycle-by-cycle precision for each needs further research.
====Partial cycle-accuracy====
This focuses on replicating the timing of instructions and key internal operations, while simplifying or skipping some less critical details. This can lower the performance requirements compared to full cycle accuracy.
