Probably one of the best explanation ever heard about romsets differences (merged...). Thx for that!!!

I've actually been watching a ton of videos regarding Mame and Launchbox setup, and I just need to come forward and thank you for making this detailed and extremely informative video on the subject. Your dialogue is clearly spoken and neatly scripted, and the video is to-the-point without missing important points of the setup process or rambling on about something that is probably obvious for most Arcade game enthusiasts who are new to Launchbox setups. Sincerely, you've done a fantastic job here! Some other questions bouncing around my head on the subject that you may consider for future videos are; what are the differences between versions of romset over the years, are there advantages going with an older romset over a newer one, and why they aren't backward compatible, is it possible to convert a split romset to full-non-merged, is Retroarch worth a look and if so, how to set up RetroArch for Mame or FBNeo, are FBneo romsets different from Mame sets? Setting up an arcade or console emulation computer or mobile device is trickier than I initially imagined, and I greatly appreciate your efforts to help me explore these topics with your videos.

I’m new to mame as well and this really helped me out. Thanks for the great guide!

FINALLY, thank you! Straight to the point, no insignificant information. I wish more videos chose the same delivery as you here. Big thanks. Subbed and liked.

You are doing the lords work my friend

Very nice guide! Might have been worth mentioning the All Killer No Filler batch files that can be downloaded from the arcade controls forum. These batch files allow you to pair down any MAME ROM set down to around 650 of the 'best' games, which is still more than enough games!

T|his is amazing have used bigbox on all my arcade machines for a while now so my arcade files were so streamlined never thought to do this just exported them all to my 351p now you make my life so much better!

If you can believe what I tried to do lol. I was trying go through a full non-merged romset and manually pick out the working parent files one-by-one. I completed #-B, which took about 1 hour, before I gave up. I knew it would take me about 2-3 full days just to get the roms I needed. But then I came across your video which showed that all I had to do was trim the set and export them via Launchbox. It took only 1 minute. You saved me days of work. Thanks.

Its worth noting that Launchbox imports its MAME games based off of several sources that are combined to create the working games list. This list is much more current then the games from say a MAME2003 romset. So Launchbox will show some games that you dont actually have and wont be imported. Just a heads up for people using MAME2003 sets.

I've recently downloaded the entire MAME 0.246 ROM and CHD sets and I know I'm not gonna be playing all of them on my Steam Deck. This video is sooo useful for cutting down which games I'm gonna import into my SD card!

Subrscribed to you for your Steam Deck coverage with the Emudeck and went down a rabbit hole which led me to MAME. Thank you so much for this! I downloaded the ENTIRE MAME library (so far) and noticed that majority of the games were BS. Thank you for this tutorial for noobs like me.

Thank you russ, I finally manage to do something I've been trying for ages with this method.

Im complety New to mame games. Would love to see a video with your favourites like a top 20 or something

I was wondering what the difference in romsets were just yesterday. Very good video, never knew this was possible. Love it. I've learned a lot about mame roms today

Days ago I was after a set of mame roms but got intimidated by all the terms and acronyms and gave up almost instantly lol But now I think I'll give another try. And I would love a LaunchBox guide from you, it is also another intimidating corner of the emulation world.

This is great! Do you have any advice for those of us who download the FB Neo romsets? This process of getting launchbox to import those seems to be not straightforward with those.

life saving tutorial, I am very thankful

Brilliant guide thanks mate 👍

Woooooow, you are a life saver!! Thanks dude!

This guide is so helpful

This video needs an update. Launchbox wants a full legit MAME set version (which 2003-Plus is not) and then even if you do pick a version, it wants to install MAME for you and selecting prefer 2 player doesn't work. I did everything in this video and ended with 4 player versions of every game that had that option :(

...a popcorn ad just rickrolled me

Thank you so much for making this video

What should I select as the import method if I'm using the Final Burn Neo set? It's not the same as MAME and FBNeo isn't an option in Launchbox. The title of the video seemed to suggest you'd explain the method for final burn too, unless I missed something.

Excellent video!👏👏👏

@Retro Game Corps How do I do this with FBNeo romset

The new one, 13.15, is NOT the same as what's shown here which is V11.7.

SO i got a splitset from pleasuredome and launchbox says it's not a full set... i tried manual installation of the mame emulator but nothing is working.

launchbox now asks for full set version on the wizard and i don't know what to use. i got the mame 2003 plus reference set 2018 (non-merged full)

Incredible video, I mess around with a lot of assorted emulation, but have always steered clear of MAME since I didn't really know how to reduce the games to just what I want to play. Big game libraries look impressive, but I try to limit my launchbox to my top games from that console (usually 10-20 games) and then a bunch of fan favorites and maybe a couple obscure ones I want to try out

Can you use the same system to remove duplicates on other systems too? Or is it just for MAME?

This is an awesome guide, what do you suggest I use to trim other emulators' romsets? I'm currently using a no-intro romset (for the quality), but there's way too many roms for my 64 gig SD. I'm currently messing with launchbox to try to do this, but it's really tiresome

i went from a 8k fbneo romset to a excellent 2.7k romset full of goodstuff

Can you please make a video for FBNeo full non merged romset? With the latest Launchbox if you can.

Hi, I try to get run Ruffle in fullscreen with scale=showAll and forceScale=true. Here is my default line parameters command in launchbox: --fullscreen --scale=showAll --forceScale=true Like this Ruffle won't launch at all, if remove command line than emu is running without any issue but no parameters apply.... Really need help on this one please.

The "region to prioritize option" doesn't work for the games. I select "North America" but launchbox keeps choosing European games over American games. I'm starting to believe the it only works for the media.

Thanks for all the video's you do, they have helped me immensely set op my RG350M. Just struggling at the moment with exporting my tidied 2003 Plus romset from the 12.7 version of Launchbox, after importing the romset and tidying it it says there are no files to copy to my new destination...any idea's ?

Thanks for videos! I bought an RG351p and I’ve been watching your videos for setting it up. One question I have is with the mame emulator. For some reason I cannot play any of the roms on mame because ‘select’ is not ‘inserting coins.’ Any information would be great!

How do you select all the games for export?

Hello. I have a question, i have the latest LB and BB and i have fullromset 2003 non merged. When i try the "import an arcade full set" so i can do all those steps to trim down my roms it asks for the specific romset. But it goes from 0.162 all the way up to 0.259. How can i import the full romset if it does not have the 0.78 (i think that is the 2003 plus)? in your video it does not ask for the version. Can you please help?

awesome video!

Very well done video

So you selected 2799 games and it saved 2081 zip files. Can you explain what games got lost here or are you just going to make guesses like you did before? Basically this is a poor method and you dont know what happened to those files.

Nicely done - excellent and very clever. I just don't understand how when you were explaining the different type of romsets, you didn't mention merged sets. One guy says merged non-merged, split; you say full non-merged, non-merged, split and another says all of them - full non-merged, non-merged, split and merged. No wonder it's so confusing. We're not all on the same page.

FINAL EDIT!: it worked! So I never had mame or LaunchBox installed on my windows computer, because I go to my moms house to use hers: I use linux and Mac. Once I installed both MAME, Launch Box, AND set the rom path in mame to the folder with the full non-merged roms, then went ahead with the super well detailed and awesome instructions on this vid. Leaving this all here in case someone else runs into this!!!!! So this isn’t working for me!!!! I’ve gotten to the point where it’s time to export the roms, but I’m getting an error after I select what folder to export it to “No ROM files were found to copy to the destination folder.” And this is after it already supposedly removed duplicates. Any help would be great! Edit: I notice you have a licensed version of launchbox. Maybe you can’t do this in the free version? Edit 2: I installed launch box just to do this. So I also had to install the mame emulator as well, and was told make sure that the rom path of mame was the same as the path you’re importing from. It seems to be working differently this time. Let’s hope for a positive result!

This video's a bit old, but i'm trying to scrape my roms which is a merged set w/ the chd's in folders now because thats a thing and skraper is only checking a folder that doesn't exist for some reason and is completing it's task in 3 seconds.

Nice video, very informative ! Can we trim a ROMs collection by Systems ? I'd like to have only say CPS1 and 2 ROMs ? Thanks

Can you help me understand how to do with FBNeo?

I wonder if you can make a video on how to run MAME games on the Retro FW 2. The Mame4All emulator just doesn't want to find any of the games, pretty sure I am using the right rom sets, but I also tried many many different ones.

This works perfectly for me until I got to export the roms. Launchbox is saying I don't have any roms to export, but I'm looking right at them. How do I fix this?

and where do i download the full romset non merged? i can only find merged ones

I just rewatched your video and you are having the same issue I am with trimming down the set. You selected 2799 games and hit export but it shows you only got 2081 games exported? Any thoughts? The reason I care so much is that i know I've lose several good games when it cut down the list by that much. Thanks in advance!

for some reason when I try to export to a file it cant find the roms, I have tried to point mame to the roms, use different versions of mame, but no luck

How does this affect Retroarch? Will it get upset if we re import that slimmed list and the content doesn’t match the core? Or will it be ok because the merged rom set?

Excellent video as always. Question about what to do with all the scraped media that is now on my SD. How can I import this media into retroid pocket 3+ daijisho or other front end?

any idea how to take a merged set into a non merged set? I'm trying to curate a folder for fbneo on my rg351v

I only want to download one game (NFL Blitz). I download the .zip and chd, but when I go to import it into Launchbox, I get an error saying "The folder does not contain a full MAME ROM set" So, what files besides the NFL Blitz zip and chd do I also need to download in order for LaunchBox to recognize them? Or, should I import the games into Launchbox a different way instead of doing the import "Mame Arcade Full Set"

Curious, I followed your launchbox and media scraping instructions for an nes romset, but when I put the roms back on my RG351 it doesn't seem to see the media. No box art and no videos. I looked at the file paths and noticed the other sets I scraped from the device itself didn't have a media folder for the images and videos, so I changed that but it didn't help.

Is it only me, or is this method not actually usable for Final Burn?

Nice video ,i can get killer instinct mame rom + chd to run but its very slow and sound stutters ,how can this be fixed cheers

hi, when I import the FBneo roms it asks me for the MAME ful set version, what should I do? Thanks and congratulations for the video.

So ive been able to trim my rom set down to a more managable number as you describe here but when I export 2000 games to a folder it actually only exports 1600? It says its going to export the full 2k but only 1600 ever show up as exported. I've been looking on the forum to see if anyone else has had this issue. Thanks!

Ctrl + A: Select all items in a window

this doesn't seem to work with an FBNeo romset. :(

What is this handheld console you have?

is their a way to get chd games to run on the rg351p? I've tried everything

Can't get any FBNeo roms to work on Launchbox. Pisses me off. I pay $75 for this and it works fine on every free frontend I have ever used. Paying that type of money should work outside of the box guaranteed.

Hey, I keep running into the same problem around 6:55 everytime I try to explore the roms I get hit with this message “No ROM files were found to copy to the destination folder.” I am very confused and don't know how to fix this everythingone going great up until this point please help!

So, you selected 2799 games and it saved 2081 zip files. What happened to those 718 rom files.

can i do this with fbneo rom set ? i have already sorted mame romset thanks for this one 💕💕

Is there any good linux alternative to do this?

Do you have a link to the rom set you downloaded as I don’t know what a good one would be due to the large amount of choice. Thanks for the video!

launchbox with mame has changed a lot, it asks for more things now, and it gave error messages several times and froze my pc.... this guide does not work anymore, sorry

There are 2799 games in your library but after your export there are 2081 rom files only. Why is that?

Does this work the same using a FBNeo rom set? I'm always having a hard time getting roms to run on different setups. I love these games but it's all very frustrating!

Does this work for daijisho?

Do you know why this method would delete '3 on 3 Dunk Madness' from a Non merged FinalburnNeo set? I've tried different variations but no idea why it would get rid of that game as it then makes me wonder what else it gets rid of. Only now LB asks for what MAME version you have (even with FinalBurn sets) so maybe its to do with that. Any ideas? Thanks for the vids mate been a really big help.

does it work with xbox 360 jtag mame roms?

i dont find this work for fbneo

damn bro i just wanna delete the multiple language versions out of all my no-intro sets... shit is so frustrating! i literally spent all yesterday doing this and still have A LOT to go. I've been using the windows explorer to search a folder with like "USA" or "Japan" but its not very precise and I worried, in fact sure that there are exclusives I'm deleting when i clear out hundreds of files at a time bc there are certain ones that are japanese but play in english also. But im so fed up with it all im just doing it and really only keeping the USA versions. certain sets are an extra pain in the ass though bc they dont use "USA or JAPAN or EUROPE" and instead use just (J) and that doesnt work just putting in J in the search, or even (J). bc while it shows it, it also shows anything with a j in it. I'm just so tired of this man... like why on earth arent these rom sets split into language???

duse this still werk?

Thanks for this guide. Works perfectly with MAME. But how to do it for FBA or FBN?

How to create separate CPS1,CPS2 etc sets for the RG351P?

This method seems to work pretty good, but certainly isn't foolproof. Using this method, Rush'n Attack gets excluded from my set, and I'm not sure why. It was a North American title that doesn't seem to fall under any of the excluded categories. This makes me wonder how many other legitimate titles get left out of a "perfect" set.

What's the point of getting a full rom set? Maybe just when you want to play a game get the game and then play the game. Don't get a thousand freaking games that you're never going to play lol.

Yeah this doesn't work unless you have all the emulators set up in launchbox first. This was a pain.

First, good guide. Well presented. Small correction. It has 4863 zip files. (Approx). Not roms. The roms are in the zip files and there are many times more than 5000 ROMs. It could confuse some people if you call the zip files roms. Whomever decided the naming conventions of split/merged romsets should be shot by the way. Split, merged, non-merged, summersalt, peachesncream, all nonsense

Does this work for the Retro pocket 2

Do you have a video showing where exactly to get this rom sets ?

Does this still work with Launchbox 12.11?

The 8 people who disliked this video. I hope your sd cards get corrupted...

When I try this, none of the bios files transfer over. Example is neogeo.zip.

Cheers! I was in the middle of doing it manually when I gave up and thought I'd search KZfaq. Super easy to follow 😀
