PS2 EMULATOR

The PCSX2 project has been running for more than seven years. Once able to run only a few public domain demos, recent versions enable many games to work at full speed, including popular titles such as Final Fantasy X or Devil May Cry 3. Visit the PCSX2 homepage to check the latest compatibility status of games (with more than 2000 titles tested), or ask your doubts in the Official forums.
