In 2021, a significant development in PlayStation 2 (PS2) emulation was the addition of support to the Play! emulator (version 0.43), released in August 2021. CHD is a compression format originally developed for MAME that allows for high-efficiency storage of disc images without losing data. Key Benefits of CHD for PS2 Games
A: Generally, yes. For Final Fantasy X , ISO = 4.5GB, CSO (Level 9) = 2.1GB, CHD = 1.9GB. CHD wins on compression and integrity checks.
