Anyone who has even spent some time playing on an emulator knows what a savestate is. They're useful and can be invaluable when you're in a very difficult area of a game, but commercial games and consoles don't usually support the savestate feature.
This plugin itself is called PspStates and, as you may have guessed from the title, it lets you create savestates while playing games on your PSP Slim. Not in an emulator, but on your handheld itself. And yes, it's for Slims ONLY.
With this plugin you can manage your games' save states and slots with an easy to use menu. hiroi01 has updated the PspStates Menu to include a picture of the save state.
