File used by PCSX2, a PlayStation 2 (PS2) emulator; contains a memory card image which can include saved user data; can be opened with the program mymc in order to extract saved games and convert them to formats such as .PSU.

PCSX2 uses .P2S files for saved states (or files without an extension in earlier versions of the software). NOTE: Sharkport, a PlayStation 2 accessory, also uses the ".ps2" extension, but for saved games instead of memory card images. Therefore, if you receive a PS2 file, you may need to test for both PCSX2 and Sharkport file types.

Saved game file created by Sharkport, a PlayStation 2 (PS2) hardware accessory used for transferring data to a PC; contains a PS2 saved game but in the Sharkport file format; used for sharing saved games with others via email and the Internet.

The ".ps2" extension is also used by PCSX2 (PlayStation 2 emulator) memory card images. However, the Sharkport and PCSX2 ".ps2" formats are not compatible with each other. Therefore, if you receive a PS2 file, you may need to test it with both Sharkport and PCSX2. PCSX2 uses the .P2S extension for saves. Sharkport PS2 files can be converted to other PlayStation 2 save formats using PS2 Save Builder. However, you first need to change the ".ps2" extension to .MD, the extension used by previous versions of Sharkport.
