Does Sony allow PS1/2/PSP emulation legally?

Can PS1, PS2, and PSP emulation be done on devices such as Android or PC, with Sony's permission?

This inquiry is not regarding the legality or possible legal repercussions.

I am simply wondering if Sony allows the emulation of their consoles if I own the console and game myself.

Additionally, I am curious if there is any distinction between using downloaded bios and roms from games I own versus manually extracting the files.
