because PS1 games used 33MHZ, ps2 games used 233MHZ, software emulation for last gen isnt that great of an ideam the consoles of yesterday use a lot more power the you would think, thats why it take about 200+ MHZ to emulate a SNES game, or over 1 GHZ to emulate a N64 game, its just not practical becuase eahc system is made to run certain games, and to add all the programming in and everything takes a LOT more power. so a PS2 game at 233MHz would take around 4GHZ, assuming that a SNES with 10 MHZ takes 20X more power, i would think a newer system would take at least that much more propotionatly.
