Hashes Note: For NoNpDrm, as the “ROM” consists of a folder multiple sub-folders and files, you will want to use the “dir2dat” function of clrmarepro with 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 this zip and comparing the datfile that clrmamepro creates with this pre-made datfile . Currently there is no solid solution for “directory hashing” that supports SHA256, so you can leave that out.
