## Region detection and BIOS images
|
||||||
|
By default, DuckStation will emulate the region check present in the CD-ROM controller of the console. This means that when the region of the console does not match the disc, it will refuse to boot, giving a "Please insert PlayStation CD-ROM" message. DuckStation supports automatic detection disc regions, and if you set the console region to auto-detect as well, this should never be a problem.
|
||||||
|
|
||||||
|
If you wish to use auto-detection, you do not need to change the BIOS path each time you switch regions. Simply place the BIOS images for the other regions in the **same directory** as the configured image. This will probably be in the `bios/` subdirectory. Then set the console region to "Auto-Detect", and everything should work fine. The console/log will tell you if you are missing the image for the disc's region.
|
||||||
|
|
||||||
|
Some users have been confused by the "BIOS Path" option, the reason it is a path and not a directory is so that an unknown BIOS revision can be used/tested.
|
||||||
|
|
||||||
|
Alternatively, the region checking can be disabled in the console options tab. This is the only way to play unlicensed games or homebrew which does not supply a correct region string on the disc, aside from using fastboot which skips the check entirely.
|
||||||
|
|
||||||
|
Mismatching the disc and console regions with the check disabled is supported, but may break games if they are patching the BIOS and expecting specific content.
