Compression Level

Controls how hard the tool works to compress your file.

Level Speed Size Best for
Fast ⚡⚡⚡ Bigger Testing
Normal ⚡⚡ Balanced Daily use
Max Smallest Archiving

Default is Normal — good balance for most people.


Verify after conversion

When enabled, OpenROM runs a checksum verification after every CHD conversion using chdman verify.

Should I enable it?

  • Yes if you're archiving and want to be sure
  • Skip it if you're converting a lot of files and trust your storage

Default is ON — keep it on unless you're in a hurry.


Tool Paths

By default OpenROM uses the bundled tools in assets/.

Only change these if:

  • You want to use a newer version of chdman/maxcso/etc
  • A bundled tool isn't working on your system

Leave them blank to use the bundled versions.


Log Files

Logs are saved automatically to:

OS Location
Windows %APPDATA%\OpenROM\logs\
Linux ~/.config/openrom/logs/
macOS ~/Library/Application Support/OpenROM/logs/

Useful for debugging failed conversions.
