Pcsxbox is a port of the Playstation emulator PCSX to the Xbox. For most Xbox releases there is no download link due to XDK, so I gess you'll have to google around a bit.
Analog support ( tested on Medievil ) Go to the game configuration screen, and toggle the controller type for controller 1 through 4.
Multitap support ( tested on MicroMachines v3 ) Go to the game configuration screen and toggle "Multitap".
