thats the problem about emulation : you always need much more cpu power then the console you want to emulate.
ps1 for example had 33mhz and still wont run good on most 300mhz x86 cpus.
Todays cpus are very good in performance per clock (pentium 4 and d were not), so we can emulate at about 5 times higher clock.
That does sound much, but it is not at all.
if you compare with some risc cpu in mobile phones for example, you need even more power.
for example : emulating good old snes with ~3mhz is impossible with full speed on a 400mhz ARM cpu in some pocket pcs.
We should be happy of what we allready got.
The future will be much worse. Even emulating ps3 or xbox 360 will be impossible the next maybe 10 years as per core computing power does not increase by much.
