ClrMamePro vs One ROM Studio

ClrMamePro scans and rebuilds MAME machine sets, checking ROM, sample, and CHD files for missing, unnecessary, or incorrectly named files. Its Rebuilder matches input files against a database using hashes and size, then writes correctly named machine files to an output folder. The package includes a graphical interface and a command-line executable with Scanner, Rebuilder, and Dir2Dat functions. The tools can use a MAME executable's listxml or listsoftware export as a data source. They use 7z.dll for 7z archive support and can produce zip, 7z, or decompressed output. A suitable DatFile allows use with systems beyond MAME. There is no install wizard; users unpack the archive into a folder. Current builds run on Windows 7 and higher, while older documentation describes Linux use under WINE or similar. The software is freeware, and the copyright notice identifies Roman Scherzer as its author; he says he started clrmame(pro) in 1997. Incorrect settings or removal operations can cause data loss, so the author recommends backups.
