PS2emu is a Playstation emulator by Roor, shunt, and Scar_T. Please note that you will need BIOS files to use it(SCPH10000.BIN and ROM1.BIN).

NeutrinoSX2 (nSX2) is an open source emulator for the Play Station 2 platform. Just as the other emulators of its kind, its still under construction, so yeah it means that you can't run any commercial game with it. In order to run this emulator at its full speed with all the options turned on, you should have the recommended requirements: * Intel Pentium 4 2.0 GHz (or AMD XP) * 512 MB RAM * 5 MB free disk space (for nsx2) * 200+ MB free swap space. * MS DX9 compatible hardware * MS Windows XP * Latest DirectX * Powerful Video Card (Nvidia Geforce or Ati Radeon)

World's first Playstation 2 emulator. This is the first PS2 emulator that slowly shows us that commercial games might soon be fully playable! As you might recognize from the name, it was developed by the team behind the PS One emulator PCSX. It was developed by reverse engineering PS2 demos, which isn't an ideal source for developing an emulator. It simply is far from complete. But at least it's a start, so if you want to have a look, here it is.
