DeSmuME PSP is a port of modern stable DeSmuME based on the initial port by HCFcoder. It is completely unoptimised in its current state.

The plan is to use a dynamic rebalancing system to emulate both the ARM9 and ARM7 processors on the main CPU and Media Engine, depending on which CPU has more resources available at any given point. It is hoped that with both the main CPU and ME working in tandem, many games will run well.

Currently, the port is very basic. Everything is done on the main CPU (including all graphics and rendering) so it is very slow, and SDL is used as an abstraction layer for many parts (eg. input) rather than native PSP calls.
