.PS2 File Extension
File Type 1PCSX2 Memory Card File
What is a PS2 file?
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.
