Techicaly, its possible. You need the Bleem! emulator or an equivalent and a load of computer power, although todays average machine should manage it.

Legally, Bleem! got sued into oblivion over the inclusion of the BIOS ROM although Sony would hae jumped at any excuse to shut them down. I don't know whether there are any current sources of it or whether there are any equivalents, but PS emulation is legally dubious at best.
