This is the gold standard for PCSX2. It compresses the game data significantly—often reducing a 4GB ISO to 1.5GB or 2GB—while remaining fully playable. PCSX2 reads it just like a normal disc.

With modern tools and the nightly builds of PCSX2, compression no longer means compromise. You can enjoy the PS2's golden era at a fraction of the storage cost, running smoother than ever.
