From Retro Arcade Guides

This torrent is a compilation made by the Pleasuredome staff of files from different sources.

The files are used by the MAME emulator or by frontends. They improve the playing experience.

All the contents of this torrent can be obtained from the websites of the original authors.

From the very beginning this torrent was made to be instantly usable while seeding back the contents.


The MAME EXTRAs, MAME Multimedia and MAME EXTRAs Update torrents are usually released every two months, about two weeks after the MAME release. It's necessary to wait until all the content is up-to-date and made available by all the sources used. They will always be behind because there is no way for the source to start creating the content any sooner than after a MAME release. The 3 torrents are released together. Do not ask when or if a new version of this torrent will be released, it will be released when it's ready.

The VideoSnaps (short videos intended to be played by frontends as previews) and Soundtracks (in MP3 format) are actually part of the MAME EXTRAs, but due to the size they are in a separate torrent named MAME Multimedia.

The MAME EXTRAs Update torrent has only the new files required to update both the MAME EXTRAs and MAME Multimedia torrents from one version to the next version.

Reproducing the torrent's contents

The files that are provided by progetto-SNAPS can also be downloaded with Arcade Database Tools.

Below are three methods to reproduce the torrent's contents using ROM Managers:

Method 1 (slow)

- Download the update set, if available.

- If you own a previous set, unzip all the existing zipfiles that contain the non-zipped content into a folder of the same name (in 7-zip -> Extract to "*\").

- Create a temporary folder called "_scan" in the parent folder.

- Move all the (extracted) folders with the non-zipped content into the "_scan" folder.

- Load the "all_non-zipped_content.dat" into CMP and in the Settings, point at the temporary "_scan" folder.

- Scan/Fix*/Rebuild the content until it's 100% complete and use the update content as rebuild source.

* Note: In case of Datfile Problem messages -> Yes To All

- Zip the internal content of all the individual folders in the temporary "_scan" folder and torrentzip (64-bit) them afterwards.

- Move the zipfiles from the temporary "_scan" folder to the parent folder.

- When all is finished, delete the temporary "_scan" folder.

Method 2 (fastest)

- download the Update EXTRAs

- create a folder "MAME EXTRAs\_scan"

note: replace by the current MAME EXTRAs version

- load the all_non-zipped_content.dat in CMP and point it at "MAME EXTRAs\_scan" in the Settings

- scan (New Scan without fixing) the empty "MAME EXTRAs\_scan" folder

- rebuild from the previous full version and from the current Update EXTRAs

- scan (New Scan) the result, which should now be 100% complete

- zip the internal content of each folder (except dats and folders) in "MAME EXTRAs\_scan"

- move the zipfiles and the dats and folder folders to "MAME EXTRAs\" and delete the _scan folder

- drag 'n drop the zipfiles on Torrenzip.NET (way faster!) or trrntzip64.exe

- scan/fix/rebuild and torrenzip the artwork and samples, using their datfiles

- copy the cheat.7z to "MAME EXTRAs\"

- check if it matches the torrent and join.

Method 3 - Using RomVault and a script created by member kdin6tl3nm (fast)
Updated script by Fragoulin here / Rust alternative by Fragoulin here / Python alternative by methuselah here.
Older versions: Originally written by kdin6tl3nm here / Old fix by Fragoulin here.
  1. Download the MAME EXTRAs dat-files zip.
  2. Download this script.
  3. Extract the script (cvt.vbs) from the zip to an empty folder.
  4. Put the zip with the 3 dats inside in the same folder of the script.
  5. Double click the cvt.vbs script to run it. A single dat-file will be generated.
  6. Copy the new dat-file to the RomVault\DATRoot folder.
  7. Copy the "MAME Extras" files of the previous version to the RomVault\RomRoot folder.
  8. Copy the latest "MAME Update Extras" torrent files to the RomVault\ToSort folder.
  9. Delete all cheat.7z files from the RomRoot and ToSort folders. They would take hours to process.
  10. Run RomVault and press the "Update DATs" button on the left. Then press the "Scan ROMs" button. Then press the "Find Fixes" button. Then press the "Fix ROMs" button.
  11. Close RomVault.
  12. Copy the latest cheat.7z to the RomVault\ROMRoot folder. Remember that RomVault always creates torrentzipped zip files, but this archive must be left untouched.
  13. TorrentCheck will tell you that, and should be unzipped.
  14. The RomVault\ROMRoot folder contains the result. Move its contents to another folder so that you can seed with your bittorrent client.
