Rename game titles with the help of Datfiles

Available since 1.8.9.4 beta 4

You have Roms whose filename is not correct and which sometimes cannot be found during a scrape. ARRM allows, based on their CRC32 / MD5 to look for the correct name in the Datfiles, by selecting the Roms and by clicking on Rename with DAT Useful for correctly scraping when the roms filenames are not correct.

Since version 1.9.1.2 beta 3

If the system is one of the Arcade systems declared in the %appdata%\Nexouille Soft\arrm\Database\arcade_systems_list.txt file, the search will first be done on the file name which, in Arcade, is normalized and the result will be very reliable.

Available since 1.9.1.7 beta 9

If the system is part of the Daphne/Singe systems declared in the file %appdata%\Nexouille Soft\arrm\Database\daphne_systems_list.txt , the search will first be made on the short name which, on Daphne/ Monkey is normalized.
If the system is one of the ScummVM systems declared in the file %appdata%\Nexouille Soft\arrm\Database\scummvm_systems_list.txt , the search will first be done on the short name which, on ScummVM is standardized.
If the system is one of the ScummVM systems declared in the file %appdata%\Nexouille Soft\arrm\Database\pcdos_systems_list.txt , the search will be done first on the filename.

If the previous search returns nothing, the search will be done via MD5 / CRC32

Since version 1917 Beta 9 These files are editable via the Tools tab see: ARRM software setting

Please note that this renaming is not 100% reliable, sometimes the names found are not the correct ones

For Arcade systems, since version 1.9.0.2 Beta 15, it is also possible to use Rename Arcade game titles

Rename game titles with the help of Datfiles

As a precaution save the gamelists.xml of the affected systems.

Select the system (only one) then click on Display

When the Database is filled with the Roms found,

Select the Roms of which you want to find the right title with the help of the DATFILES files.

You can apply the Clean Name , Add Disc and Add Country checkboxes which will apply to the title found.

Click on the button Rename with DAT

Validate the confirmation popup.

ARRM will start a calculation of the CRC32 and MD5, then look for a match in the Datfiles database. If a match is found, the game title is changed to the one found in the Datfiles.

A CSV file is generated (rename_with_dat.txt) at the end of the operation that indicates which Datfiles the matches come from. This file can be used in Excel (separator |) It's located in this folder : %appdata%\Nexouille Soft\arrm\temp

Update the database with new Datfiles (.dat)

Available from version 1.9.0.2 Beta 8

It is possible to update the ARRM database with new datfiles (.dat) to be able to use the Rename with DAT function.

To update the ARRM database you must put your datfiles (.dat) files in the folder:

%appdata%\Nexouille Soft\arrm\Database\tosec

Then click on the DAT to Database button present in the Update tab. ARRM will browse all the .dat files present and update the database with the new information collected. It can be quite long.

When a .dat file has been processed, you can remove it from this directory, otherwise it will be scanned again the next time the DAT to Database button is pressed.

Update Arcade database with new Datfiles (.dat/.xml)

Available from version 1.9.1.2 Beta 3

It is possible to update the Arcade dedicated ARRM database with new datfiles (.dat/.xml). This Arcade database is used with the Rename with DAT or Filter Arcade Clone function on Arcade systems. As a reminder, Rename with DAT makes it possible to find in the ARRM database, the correct title of an Arcade game based on its file name (standardized for Arcade) while Filter Arcade Clone allows you to filter out Roms that are clones of other Arcade games. To update the ARRM database you must put your DAT files (.dat or .xml) in the folder:

%appdata%\Nexouille Soft\arrm\Database\dat

then click the Arcade to Database button. New records will be added or modified to the existing database. It can be long.

You can see which .xml or .dat file format is compatible by looking at the files present in the folder:

%appdata%\Nexouille Soft\arrm\Database\dat\samples

These .dat/.xml files must respect this structure.

When a .dat / .xml file has been processed, you can remove it from this directory, otherwise it will be scanned again the next time you press the Arcade to Database button

Format of the Datfiles (.dat)

Since version 1.9.1.2 Beta 3, you can see which .xml or .dat file format is compatible by looking at the files present in the folder:

%appdata%\Nexouille Soft\arrm\Database\dat\samples

These .dat/.xml files must respect this structure.

The format of the Datfiles (.dat) files must respect this format. The information sought by ARRM is indicated in red, the others are ignored by ARRM

ARRM also recovers the md5 if it is present:
