You cannot convert a lone BIN to CHD without knowing the sector layout. Use a tool like CueMaker or ISOBuster to regenerate the CUE sheet from the BIN file.
The Ultimate Guide to CHD PSX ROMs: Efficient PS1 Emulation For retro gaming enthusiasts, PlayStation 1 (PSX/PS1) emulation has long been a staple. However, managing a large collection of PS1 games—traditionally stored as .bin and .cue files—can quickly consume hard drive space and create a cluttered, messy library.
