A write-up on verified CHD PSX ROMs focuses on the gold standard for PlayStation 1 (PS1)

ROM managers were built for MAME, but they work perfectly for CHD files.

CHD is a lossless compression format. This means that while the file size is significantly reduced (often by 40-50%), no actual game data, audio, or video quality is lost during the conversion.

Netplay & Achievements: Platforms like RetroAchievements often require a specific, verified hash (like CRC32 or SHA-1) to recognize the game and unlock trophies.
