indeed it would be great but it is impossible for now
.
There is an emulator for pc named jpcsp and it can run some games at a playable speed but you need at least 2Gb of ram and 2+Ghz computer not to mention a awesome graphics card also a good cooler because otherwise the system will catch fire( ok i might over do it
).
Psp cant be emulated on the android phones at least not for now
