Tips and Troubleshooting

Make sure you have a compatible CHD file and that it's not corrupted.
If you encounter issues loading the CHD file, try re-configuring ePSXe or checking the file for errors.
For better performance, consider adjusting ePSXe's graphics and sound settings.

By following these steps, you should be able to play CHD files on ePSXe. Happy gaming!

1. The CD-ROM Plugin Settings

ePSXe relies on a CD-ROM plugin (usually ePSXe CDR or Mooby's CD).

Set Read Mode to "Async" (Asynchronous): This allows the emulator to keep decompressing data while the game runs. Without async, you might get micro-stutters.
Increase Subchannel Reading: Some CHD conversions preserve subchannel data (for LibCrypt protected games). Ensure "Read Subchannel" is checked in your CD plugin.

Error 2: "Missing CUE file" when converting back from CHD

Cause: When you extracted the CHD to BIN, chdman does not automatically recreate the CUE sheet for audio gap preservation. Fix: Use the -f (force) flag during extraction, or originally included the CUE data. Run: chdman extractcd -i game.chd -o game.cue -f

Part 3: How to Convert CHD Files to BIN/CUE for ePSXe

Since ePSXe cannot read CHD, we will convert them back to the standard .bin/.cue format. You will need a tool called CHDMAN (part of the MAME tools).

Method 3: Using PBP Format (The ePSXe Native Alternative)

If you want to stick with ePSXe but want a single, compressed file format, you should use PBP (PlayStation Portable format) instead of CHD. ePSXe supports PBP natively.

Use a tool like PSX2PSP.
Convert your ISO/BIN files to PBP format.
Load the .pbp file directly into ePSXe.
