The real-world result of the CHD format's efficiency is a vibrant community of retro gamers who have been able to build massive, well-organized, and portable game libraries. The format has become the standard for "ROM packs" used on dedicated retro gaming devices like the Anbernic, Retroid Pocket, and Steam Deck. By using CHD, the community ensures that classics like Castlevania: Symphony of the Night can be easily carried and played anywhere, preserving its legacy for future generations.
A standard PS1 game typically takes up 500MB to 700MB on a disc. When converted to CHD, the size is drastically reduced. For example, the “Castlevania - Symphony of the Night (QoL v1.2).chd” file is only around . The conversion effectively cuts the game’s footprint by nearly 50%, allowing collectors to store thousands of games without investing in massive hard drives.

Before delving into the technicalities of the file format, it is crucial to understand the cultural and historical significance of the game you are about to experience. The real-world result of the CHD format's efficiency
Furthermore, with the rise of FPGA (Field-Programmable Gate Array) devices like the MiSTer and Analogue Pocket (which supports CD-ROM cores via add-ons), CHD support is becoming necessary. These devices often struggle with the raw file I/O of BIN/CUE files; the consolidated nature of CHD allows them to stream game data more efficiently. A standard PS1 game typically takes up 500MB
