For PlayStation 1 (PSX) emulation, CHD (Compressed Hunks of Data) is widely considered the best ROM format because it offers significant lossless compression while maintaining high compatibility with modern emulators. Why Use CHD for PSX?
Lossless Compression: CHD reduces file sizes by roughly 40-50% compared to standard BIN/CUE sets without losing any original game data.
Single File Management: Instead of having a messy folder with multiple BIN tracks and a CUE file, a game is consolidated into one single .chd file.
