An ISO file is a straightforward, sector-by-sector clone of a physical disc. While highly compatible and easy to mount, ISOs are notoriously bloated. Because physical DVDs often contain "dummy files"—blank data added to push game data to the outer edges of the disc for faster read times—an ISO retains this useless data, wasting gigabytes of space. Furthermore, standard file compression tools like ZIP or RAR are impractical for PS2 games, as decompressing a 4 GB file every time a user wants to play it causes massive slowdowns and excessive wear on solid-state drives. Place your

It is a common myth that compressed files slow down emulation. In reality, because CHD files are physically smaller on the disk, your hard drive or SSD has to read fewer bytes to load the game data. Even though the CPU must decompress it on the fly, modern processors handle this so efficiently that CHD often results in compared to raw ISOs, as there is less physical data to transfer.
