The emulator itself likely is legal but the psx BIOS is protected under copyright and ROM images are not legal either even if you own the title. It doesn't matter what the ROM sites say, read the original games license. According to most licenses you are not even allowed to make backup copies.that's not necessarily true. emulators are legal so long as you own the original hardware, just like roms are legal if you own a physical copy of the original title.
