Just Google it. Almost every emulator site I've seen has reviews to tell you which works best. And for PSX\PS2 emulators, most of them require the disc, so you bet they'll work with it.
Again, it's not recommended to ask this sort of question on a commercial site. Were this some sort of off-corner and a small forum run by a private individual, the admin there might not mind the discussion of such; emulators, while technically legal themselves, get quite close to the border, since their implied purpose tends to, itself, often be illegal. (though running straight from an authentic PSX disc is legal)
