Great comprehensive collection. My go to source. 👍🏻

FRIENDLY WARNING
Be careful with links posted in the comment sections by other users, once certain archives gain popularity and generate large bandwidth traffic, some people take advantage to spread links, which I cannot guarantee the legitimacy of the content nor if it's safe.

@flamesx
Archive.org uses VirusTotal API, so getting a virus from here is very unlikely.

@Luke Verhelle
You need to have the qsound roms for cps games, which can be found in this archive (search for "qsound.zip"), that will solve your issue ;)

@loiabdullah
I'm afraid Samurai Showdown V Perfect is only available for FinalBurn Neo as samsh5pf.zip

@Olddantrucker
If you don't know how to use jDownloader, you can always try the torrent method:

thanks sir

Thanks

HOW AM I SUPPOSED TO DOWNLOAD THE ROMS???!!!

Please I need help, all my Nichibutsu games are missing audio(Terra Cresta, Terra Force etc). Which roms are from Nichibutsu so I can update and try them again? I'm running MAME 0.256.

If you scan the files you will find virus warnings in several files. Please be safe.

@shadowbannedx, the most sane archive user

Edit: Finally got it to work after several tries. Hope there isn't a lot of 'missing' files like Joseph went thru.

The SL files are grabbed by JDOWNLOADER 2 but the regular ROM list isn't. To Joseph there is a lot of 'missing' files' lately on later MAME versions and you'll absolutely have A LOT of fun figuring out which letters are missing in ROM collections if you ever do torrents!.


Not surprised about missing files and issues with torrents people tend to have since this site is VERY pro communist and the people who upload all are loaded on pot or other drugs f'king their minds up. LOL. You all think your living high above everybody well guess what? Your time is running out! The 'silent' majority has had it up to here with the treatment and even beyond them we are spiritually about to wrap it all up regardless and will have to answer to the high one. NOBODY gets a free pass!

After the latest version of MAME was downloaded
some of the files are required for Taiko No Tatsujin, such as nm-002,nm-003,nm-004 and one of the CHD file for Taiko No Tatsujin 5 is missing.

I spent several weeks searching for a rom set that work with MacOS Openemu, and finally found it! Thanks a lot!
Greetings from https://mobizoo.com.br

most cps games missing dl-1425.bin and wont load. Did want to say appreciate all the work put into this. Dont mean any disrespect just wanted to let everyone know and also an easy fix to add them in I did most myself.

Please update some roms do have missing files. Please update this romset

First I'd like to thank you for all your work you doing here. It is greatly appreciated.

I tried to verify/scan the set with clrmamepro but I get tons of missing roms/sets.
I pointed clrmamepro to the mame executable for one scan (that directly extracts the dat file I think) and I tried the dat file provided by progettosnaps. Both methods resulted in a lot of missing or wrongly named files. Is this something to be expected or can you think of something I might be doing wrong?

Thank you!

In response to the rude author. Some other users besides me are having different kinds of troubles too:

I have done emulation since the Windows ME/XP era when there was just a few shitty emulators that barely worked and watched them mature into something workable so don't tell me I don't know how to manage things.

YOUR the Biden shit head and your beloved big tech is about to get smacked and ironically your beloved Biden is fighting against big tech much to my surprise.

The shitheads are those on here and you all need to have some mysterious 'accidents' happen. YOU WANT TO SEE A TROLL ATTACK? WELL YOU'VE FUCKING GOT ONE YOU SNOTTY SON OF A BITCH! I CAN KICK YOUR ASS TO THE FUCKING MOON AND BACK! YOU WANNA PICK A FIGHT WITH ME BRO? LETS GO OUT BACK AND SEE WHO'S TOUGH HUH?

La mitad de los roms no funcionan para Batocera 35, dan problemas de Bios antiguas y CHD faltantes para la mayoría de las roms

I don't know why but when I add this torrent it kills my torrent client deluge where it will stop responding and download extremely slow and unreliably, can you add a simple .zip file containing everything, also jDownloader wont download all of them either so I dont know where to find another romset.

Just rename your PD folder "MAME 0.xxx ROMs (merged)" to "mame-merged" and relive the glory of your youth with this torrent:
https://archive.org/download/mame-merged/mame-merged_archive.torrent
Then think about donation to the Internet Archive.

So, do I need the CHDs to play most of the games in this set or no? Can I use CHDs from older versions of mame?

I don't know if anyone here can help but I downloaded this mame pack from the torrent version because jdownloader was seeing duplicates of every file. But I had no issue using jdownloader for the chd files. I downloaded the mame pack here and set it up put the mame roms chds and bios in the roms folder. All the mame that require no chds work fine. The games that require chd files don't work they don't see the chd files the only one can get to work is gauntlet legends.

I've not spotted any issues with this.

I was so impressed I wrote some code to automatically download and ROMs & MAME binaries.

Just enter the MAME short/name code it does the rest.

https://github.com/sam-ludlow/mame-ao

Ignore the usual troll reviewers that don’t know how to internet.

Laid the torr over my old 0.225 merged set, only needed 8gb of changes, not found a single issue! Incredible work, many thanks!

I've recently found out there's a more-likely "ceased and desisted" rom for Samurai Showdown V Perfect and I noticed some managed having it from I don't know somewhere... Even though it's only playable via "Arcade64", But could you please make it available? I believe you're only one who can do so..
Thanks in advance..

Excellent and clean collection of roms. The zips and the CHDs are all solid - no issues running anything thus far. Thanks for your hard work!!

For anyone not sure about the best way to download these archives:
For MAME ROM Set (Merged) - No CHD
1. Click archive link
2. Use Link Grabber browser plugin to copy file locations
3. Open Free Download Manager
4. Click menu and select "Paste URLs from Clipboard"
5. Download and enjoy

For MAME CHD (Merged)
1. Click archive link
2. Scroll to bottom of page and select the torrent file

Since nobody reads. Jdownloader can't download these since they think it's a duplicate when I put them in a fresh new drive: I don't want to say 'skip' for each and every file so I'll download the file individually and/or stick to my N64.

Also CHD's need to be put in a folder with the same name this download doesn't allow that even if completed:

Jdownloader sucks on Windows 10 but it's more likely a MS asswipe decision. Part of the alt right political machine controlling all the $$$.

I'll just stick to my N64 for newer titles that require CHD's. That's the safest best route.

Edit: 2: None of the zip files have an actual CHD in them. IE: sfrush.zip has a bunch of weird files but none of them have a CDH in them.

先去找離此版本最近的torrent
然後用工具整理 最後補齊錯誤的檔就好
工具可以用romcenter

Where are Big Buck Hunter (BBH) Big Buck Hunter Shooter's Challenge (BBHSC) & Big Buck Hunter 2 Sportsman's Paradise (BBH2SP) ? I don't see them on this list.

As always! A superb upload. I thank you

QUICK HOW TO GUIDE (Guide updated 2022-05-27):

================================================================================
STEP 1 - Basics
================================================================================
1) Download and install MAME ( https://www.mamedev.org/ )
2) Know that:
a) MAME considers CHD files as ROM files, CHDs are just bigger ROMs
b) MAME doesn't care where you put the CHDs or ROMs as long as all ROMs/CHDs directories are added to the rom path configuration.
c) That means you can add the torrent directories to MAME, and update MAME's database while ROMs/CHDs are being downloaded one by one, you can also pick which ROMs to download first, read how to do this below.

================================================================================
STEP 2 - Download the ROMs and CHDs
================================================================================
1) Install and run qBittorrent ( https://www.qbittorrent.org/ )
2) In qBittorrent, click [open url] or [add magnet link], a box will pop up.
3) Paste into the box the two magnet links from above, one line per link ( magnet:?xt=urn:btih:xxxxxxxxxxxxx... )
4) Click [Download] or [OK] to close the box.
5) You should now see in the qBittorent [Transfers] tab there are two torrents being added, [MAME 0.2xx ROMs (merged)] and [MAME 0.2xx CHDs (merged)].
6) If you have waited for a minute and the torrents are not downloading, manually add a torrent tracker to each torrent, so that qBittorrent knows what peers/seeds to download from, do this by:
a) From qBittorrent [Transfers] tab, select one of the torent ([MAME 0.2xx ROMs (merged)] or [MAME 0.2xx CHDs (merged)])
b) Click the [Trackers] tab (between [General] and [Peers])
c) Right click anywhere in the tracker list for a pop-up menu
d) Click [Add a new tracker...], a box [List of trackers to add] will pop up.
e) Paste the following tracker URL into the box and press [OK]: http://tracker.opentrackr.org:1337/announce
f) You should now see [http://tracker.opentrackr.org:1337/announce] in the tracker list, watch the [Peers] and [Seeds] column, there should be more than 100.
g) Do this once for the ROMs torrent and once for the CHDs torrent.
7) Continue to the next step while the torrents are downloading.

================================================================================
STEP 3 - Find out where the ROMs/CHDs .zip files are downloaded to
================================================================================
There are 2 paths: The ROMs (70+GB) and The CHDs (500+GB). Do these steps to find both:
1) In qBittorrent: In the [Transfers] tab, right click the torrent name [MAME 0.2xx ROMs (merged)] or [MAME 0.2xx CHDs (merged)], you should see a small pop-up menu.
2) Left click [Open destination folder], a file manager should pop up.
3) In the file manager, look at the directory location ('directory' is also called 'folder' in windows).
4) Do it once for the ROMs and once for the CHDs, remember these 2 directories for the next step.

================================================================================
STEP 4 - Add BOTH ROMs and CHDs directories to MAME
================================================================================
Set MAME's ROMs directory to the two directories qBittorrent is downloading to:
1) Go to MAME's main screen (restart MAME if not sure)
2) Double click [Configure Options]
3) Double click [Configure Directories]
4) Double click [ROMs]
5) Double click [Add Folder]
6) Browse the directory tree using the [UP/DOWN/ENTER] key to select the correct directory (remembered from previous step).
7) Once you have found the final correct directory, just highlighting it is not enough, you must press [Enter] to enter it first, otherwise you'll just set the parent directory instead.
8) Once INSIDE the correct directory, press the [TAB] key on your keyboard to set the directory in MAME.
9) Double click [Return to Previous Menu]
10) Double click [Save Configuration]
11) Do this once for the ROMs directory and once for the CHDs directory. You need to add both directories for all ROMs to work.
12) If you are also downloading the partial update torrents (e.g. MAME - Update ROMs v0.2xx to v0.2xx), then you also need to add the update torrent's download directory by repeating step 1 to 10.

================================================================================
STEP 5 - Decide on what ROMs to download and how often do you run audits in MAME
================================================================================
Now that the ROMs/CHDs are downloading and the correct MAME directories are configured, you want to audit the download directories in MAME so that it will find all the newly downlodaded ROMs/CHDs .zip files.

During the audit, MAME will find the newly downloaded ROMs/CHDs .zip files and update MAME's internal database, newly downloaded ROMs/CHDs will show up in the [Available] section in MAME.

Depending on your goal and available time/bandwidth, you have 3 options:

1) Slow + Complete:
Wait for all ROMs/CHDs to be downloaded and update MAME database once (this takes much longer to see the ROMs from MAME because the file pieces are downloaded randomly across all files); or

2) Quick:
You only select a few favorite ROMs/CHDs to be downloaded, then update MAME database. You do this by going to qBittorrent, in [Transfers] tab left click a torrent (ROMs or CHDs), click the [Content] Tab, Tick/Untick ROMs/CHDs to download/not download (e.g. only tick 1941.zip, everything else unticked); or

3) Quick + Complete (Recommended):
You select all ROMs/CHDs to be downloaded, but you also enable 'Download in sequential order', so that all ROMs/CHDs will be downloaded one by one. Set your favorite ROMs/CHDs .zip to 'Maximum' priority so your favorite ROMs/CHDs will be downloaded first. Update MAME database once in a while after a new bunch of ROMs/CHDs are downloaded. You get the best of both worlds. Do this by:

a) Configure qBittorrent to download .zip files one by one:
In qBittorrent [Transfers] tab, right click a torrent, then select [torrent options...], then tick [Download in sequential order] and click [OK]. Do this once for the ROMs torrent and once for the CHDs torrent.

b) Configure qBittorrent to download your favorite ROMs first:
In qBittorrent [Transfers] tab, left click a torrent (ROMs or CHDs), click the [Content] tab, find your favorite ROM/CHD file (e.g. 1941.zip) and click on [Normal] in the Download Priority column, it'll pop up a selection of [Do not download/Normal/High/Maximum], select [Maximum]. Do this to EACH ROM/CHD .zip file you want to complete download first. (e.g. 1941.zip is on 'Maximum' priority while everything else is on 'Normal' priority)

This combination downloads ALL ROMs/CHDs sequentially one by one, and lets you to play your favorite ROMs first while the rest are downloading.

Each time one or a bunch of the ROM/CHD .zip reaches 100% download, you can goto MAME and audit the download directories, it'll add the new ROMs to the [Availabe] section, which brings us to the next step (audit ROMs/CHDs directories).

================================================================================
STEP 6 - Audit the ROMs/CHDs directories and update the MAME database
================================================================================
1) (In MAME window) Click the magnifying glass and select [Audit media for all XXXXX machines]
2) Wait for MAME to audit all ROMs and CHDs directories
3) The newly downloaded ROMs/CHDs will now show up in the [Available] section.
4) For subsequent audits, select [Audit media for X machines marked unavailable] instead in step 1, this skips the known completed ROMs and reduces audit time.

================================================================================
STEP 7 (optional) - Install MAME Extras
================================================================================
You can add extras such as in-game/title screenshots (snap/titles), cheats, etc to your MAME installation, you have two options:

1) The hard way:
This method is too complex and time consuming for the average MAME user, and is only recommended for those determined to chase after the absolute latest, for everyone else, wait a while for the new version of EXTRAs torrent to be released (see 'The easy way' below).

Download and install each extras component manually and set up your own perfect MAME, e.g. visit https://www.progettosnaps.net/snapshots/ and download [Snap > Full-Set 0.240 (pS_snap_full_240.zip)] and [Titles > Full-Set 0.240 (pS_titles_full_240.zip)] and the smaller 0.24x update packages. Decompress the snap zip, find the directory with 40000 .png files, move all the .png to MAME's [snap] directory. Decompress the titles zip, find the directory with 40000 .png files, move all the .png to MAME's [titles] directory. snap and title .png files have the exact same filename, don't mix them up. Get the cheat.zip from ( http://cheat.retrogames.com/mame_downloads.htm ), decompress it to MAME's cheat directory. You can also manually download and install the latest cabinet/flyers/manuals/etc.

2) The easy way (Recommended):
Get all the cabinet/cheats/manuals/snap/titles etc from a single [MAME Extras] torrent, it is not updated as regularly as MAME binary/ROMs/CHDs, but this way will save you a lot of work.

It doesn't matter if the MAME Extras are a few versions behind, the differences are minimal, you just see blank title/snap images on the newest ROMs, the rest works just fine. To add extras to your MAME, do this:

a) Download the [EXTRAs 0.xxx Full] torrent listed above, or

b) Copy the [EXTRAs 0.xxx Full] magnet link above (magnet:?xt=urn...)

c) In qBittorrent's window: If you downloaded the .torrent file, click [Open] and select the .torrent file then click [OK], if you copied the magnet link, click [Open URL], paste the link into the box then click [OK].

d) Set cheat.zip, snap.zip and titles.zip to [Maximum] priority in the [Content] tab if you want them to complete first.

e) Decompress the cheat.zip/titles.zip/snap.zip etc to MAME's root directory, it'll create the correct sub directories.

f) Restart MAME and check the result. If you don't see the cheat/title/snaps, double check that the decompressed directories and MAME directories configuration are the same, often the extra sub directories from the .zip aren't needed, so you move the files one parent directory above (\snap\snap to just \snap, \cheat\cheatxxxx to just \cheat).

g) To enable cheats:
i) (In MAME's main window) Click [Configure Options]
ii) Click [Miscellaneous Options]
iii) Set [Cheats] to [On]
iv) Click [Return to Previous Menu]
v) Click [Save Configuration]
vi) From now on when you are playing a ROM, press the [TAB] key and you should see [Cheat] in the menu.

================================================================================
STEP 8 - Play and enjoy
================================================================================
That's it, play your favorite ROMs and enjoy.

First of all, thanks so much for putting this ROM set together! Now my question: :)
When the torrent finished downloading, it stopped at 77gb out of 123gb. It seems the download worked, but some games (Trog, Elevator Action Returns) weren't working and I'm wondering if there was a problem with my download. Forcing a recheck doesn't cause the rest of the 46gb to download. Has anyone else run into this issue, or could my download have been corrupted and best to redownload?

Does that include the CHDs or how do we dl those too? And where do we put them? I am confused on all this.

Bear117: Pac-Man and several other variants are contained/merged in puckman.zip.

I am a bit of a newb to this. I could not find pacman.zip. There is a pacmon.zip. Has pacman been merged into another .zip collection?

Isn't the latest Romset 0.236?

The set looks pretty complete to me. Thanks for sharing it here. Is there any other free
MAME ROMset I can download or this is the most complete one?

Is there a Torrent link for this new .240 set?

It's probably my fault since I'm new to MAME, but I have the 0.240 version, and all these roms are detected as unavailable by the emulator. All of them. Any reason as to why?

.

cant someone just make a zip of all the roms and include CHDs for games that need them?! i'm tired of having to jump through so many hoops..

The torrent shared is appreciated.
However, it is interesting that my clrmamepro skips 99% of the roms and just found little matches.
Is that some kind of file format problem ?

Chad!!!! Where is your logo with the nose dude!!! You are awesome you know that right? Please tell me the logo is coming back!!!

This looks pretty complete, I can't seem to get the torrent to finish though. the last three megs just stall. But Im looking forward to diving in!
