ePSXe relies on a CD-ROM plugin (usually ePSXe CDR or Mooby's CD).
Cause: ePSXe's ISO loader doesn't recognize the CHD header. Fix: Stop trying to load the CHD directly. Convert to BIN/CUE as shown in Part 3. Alternatively, use Daemon Tools Lite (old version). Mount the CHD (Daemon Tools supports CHD natively via a plugin), then tell ePSXe to "Run CDROM" instead of "Run ISO." This treats the CHD like a physical disc in a virtual drive.
Cause: The decompression of CD audio tracks is hitting a bottleneck. Fix: In ePSXe -> Config -> Sound -> Enable "Enable CDDA" and set "Latency" to Low. Also, ensure your power plan in Windows is set to "High Performance."
I know this is an article about "ePSXe CHD files," but as a retro gaming expert, I would be doing you a disservice if I didn't tell you the truth: ePSXe is obsolete for CHD management. epsxe chd files
Modern emulators like DuckStation (available on Windows, Linux, Android, and Mac) offer:
CHD is a lossless disk image compression format originally developed for MAME (arcade emulation). It compresses disc-based games (bin/cue, iso, ccd, etc.) significantly—often saving 30–50% space—while keeping all subchannel data intact. ePSXe, one of the oldest and most popular PS1 emulators, does not natively support CHD files.

If you use ePSXe for PS1 emulation, it’s time to switch to CHD files. ✅ Lossless compression (saves ~40% space) ✅ Single file per game (no more missing .cue sheets!) ✅ Native support in modern ePSXe

No – not directly. CHD is a great format, but ePSXe is outdated regarding modern compression. If you’re committed to ePSXe for its plugin system or familiarity: I know this is an article about "ePSXe
No, it does not.
This is the most common point of confusion. The standalone version of ePSXe (v1.7.0 and v2.0.5) does not have native built-in support to load .chd files directly from the "Run ISO" menu. It natively supports .bin, .iso, .img, and .pbp.
However, there is a workaround to get them running, and there is a better modern alternative.
