-If the "ROM" consists of a folder with multiple sub-folders and files, you will want to use the "dir2dat" function of clrmarepro with {{:submission:clrmamepro_dir2dat_directory_hashing.png?linkonly|these}} settings. Make sure the "PXXX00000" directory you want to hash is inside of two empty folders, and point clrmamepro towards that first empty folder - this is so that the "PXXX00000" directory is treated as a sub-directory of the "game" entry in the datfile. You can test this setup is working correctly by hashing the contents of {{ :test_dir_structure.zip |this zip}} and comparing the datfile that clrmamepro creates with {{ :test_dir_structure.dat.zip |this pre-made datfile}} . Currently there is no solid solution for "directory hashing" that supports SHA256, so you can leave that out.

+If the "ROM" consists of of multiple directories, you will want to use the "dir2dat" function of [[https://mamedev.emulab.it/clrmamepro/|clrmamepro]] with the following settings in the "Options" section.
+{{:submission:clrmamepro_dir2dat_directory_hashing.png?400}}
+In other words, make sure only the following boxes are checked in that section:
+  * Scan Subfolders
+  * Add MD5
+  * Add SHA1
+  * Add 0-File For Empty Folder
+  * Set-Subfolder Mode
+  * Keep Archives As Files
+  * Keep CHDs As ROMs
+You can also press the Load button and load {{ :general:dir2dat-directory.d2d.zip |this}} dir2dat config file to achieve the same thing.
+Make sure to lay out the data as with the following example.

+You can test this setup is working correctly by hashing the contents of {{ :test_dir_structure.zip |this zip}} and comparing the datfile that clrmamepro creates with {{ :test_dir_structure.dat.zip |this pre-made datfile}} . Currently there is no solid solution for "directory hashing" that supports SHA256, so you can leave that hash type out.
+In the created datfile, directories, including empty ones, are represented as files with a size of "0" and a CRC32 of "-", and no other attributes. The filename is set as you would expect (e.g. "dirwithemptydir\emptydir2" for one of the directories in the example, except it will have "_" appended to it when clrmamepro is used on Windows, and "\_" when clrmamepro is used on Linux with Wine. There will also be an archive called "Default" with a single empty folder, which should be ignored/deleted.
