As of the last stable version (ePSXe 2.0.5, released 2016), ePSXe cannot read CHD files directly. It expects:

The primary appeal of the CHD format lies in its remarkable compression ratios without any loss of data integrity. PS1 games were stored on CD-ROMs with a capacity of roughly 650 to 700 megabytes, yet many titles only utilized a fraction of that space. Traditional disc images often preserved the "empty" padding, resulting in large files that quickly consumed hard drive space. CHD uses advanced compression algorithms to strip away this redundancy, frequently reducing the footprint of a game by 30% to 60% compared to a standard BIN/CUE set. For collectors maintaining hundreds of titles, this efficiency translates into hundreds of gigabytes of saved storage. As of the last stable version (ePSXe 2
