Y de existir un emulador para correr los juegos de forma fluida y con todo vas a necesitar una PC con el poder conbinado de todas las computadoras de la Nasa, CIA, FBI, MI5 y de paso el proyecto Echelon .

Edit: Hablando en serio, hasta donde tengo entendido no hay emulador que pueda imitar la arquitectura de la PS3 como para correr juegos y aun cuando lo hubiera los emuladores siempre requieren mucho mas recursos que lo que vendria a requerir el juego (EJ: Una maquina que corra al 100% el Prince of Persia dudo que pudiera siquiera levantar la version de PS3 con un emulador).

Una porcion de texto sacada de la wiki sobre emular juegos de PS2:

"A common misconception regarding PCSX2 is that a processor with a relatively high clock speed, such as a Pentium 4 or Athlon XP (the former with clock speeds as high as 3.8 GHz), should easily be able to emulate PS2 games at full speed. The PS2 has several processing units including a MIPS R5900 chip, MIPS R3000A chip, two custom vector units, and graphics chip (Graphics Synthesizer). With the exception of the MIPS R5900 (clocked at 294.912 MHz) and the MIPS R3000A (clocked at 36.864 MHz, selectable to 33.8688 MHz for PlayStation (1) emulation), all other chips run at the bus speed of 147 MHz. There are several reasons which make emulation of the PS2 on a PC extremely difficult. Architectural differences between an x86-based PC and the PS2 are substantial; emulating multiple chips running in parallel on a single-core processor is quite complex. Taking advantage of dual core processors on PCs is even harder due to the tight synchronization between the PS2 chips. The development team provides a blog, explaining technical details of emulating the PS2.[2]"


Para la 360, ¿hay emuladores?.
