Search around the forums, nearly every emulator has been re-released for Slim. I have NesterJ, DGEN, SNESTYL, and gpSP all working fine on my Slim.
eLoader is great but I really haven't found a need for it. To use it you just start it up like any other homebrew app (copy to GAME folder) and it will display a list of all the homebrews on your PSP. From there you just select which one you want to play.
