nativespeed
Native speed is a term used to describe the real-time execution rate at which software is designed to run on its original hardware. In emulation and retro-gaming contexts, it refers to the speed at which the emulated system’s CPU, graphics, and audio are intended to operate so that programs behave as they did on the original console or computer. The concept is closely tied to the system’s clock rate and its frame rate, such as 60 frames per second for many NTSC-era systems or 50 frames per second for PAL-era systems.
Maintaining native speed is important for correct timing. If an emulator runs faster than native speed, timing-dependent
Achieving true native speed can involve different approaches. Cycle-accurate emulation aims to replicate every CPU and
