hle/lle
High-level emulation (HLE) and low-level emulation (LLE) refer to methods used when emulating components or entire systems.
They're used to differentiate approaches to system implementations by how each emulator handles a given component; a high-level emulator abstract the component with the goal of improving performance on the host, sacrificing the thorough measures needed to guarantee the correct behavior. The simplicity of most consoles allow low-level emulation to be feasible.
