This will run through how to rebuild romsets for the specific version that MAME 2003-Plus needs. The principle will also rebuild to any given romset version. Using this method should make sure that all the games load successfully in RetroPie with MAME 2003-Plus.
This is showing MAME 2003-Plus because its designed with the Raspberry Pi in mind, as well as supporting a wide range of games from different versions of MAME.
** The bit about the Neo Geo bios at about 25mins in, as its included in the main MAME romsets anyway the games will work fine, you just need the unibios version if you want that specific one. *****

When I started watching this video I thought "Why is he taking so long?". But now that it's finished I've realised it takes so long so that people like me can follow it. Sincerely, thank you. I've never had much joy with MAME and have wasted probably 8 * the length of this video getting nowhere in the past. Much appreciated.

i think merged is good for building sets from. like if you keep a full up to date merged set and keep your rollbak set up to date nest to it you could easily spit out lots of sets without using as much storage as a full non merged set would.

Whilst most games would probably be fine with the update, when the version of Mame2003plus gets updated it'll likely have a slightly different xml file, so its worth updating your romsets to this new version to keep maximum compatibility.

Thanks for the Vid! I just ran through this with MAME 0.242 and I get a ton of errors on the scan, like a lot of ZIPs are missing roms. Ones that I think should be working. Also I have the BIOS files and like the idea of including them but I am not sure how to do that. Will Clrmamepro combine them? do I need to point Clrmamepro to the BIOS directory? Thanks again!

@Floob 2 жыл бұрын

Glad you found it useful :) I'm not sure which dat file you are using, but its likely once you have rebuilt with the 0.242 set, you should then also use the 'rollback' romset for 0.242 - the process will use that to fill in the gaps you have (you can run the rebuilder as often as you like against other sets to fill in the gaps). For the bios files to be in the same romset as the game, look at the 'Separate BIOS sets' option when rebuilding: mamedev.emulab.it/clrmamepro/docs/htm/rebuilder.htm

@@Floob I've never heard the term 'rollback' romset until watching this video. Is that the same thing as the supplemental update set that would update from v0.223 to v0.224 for example, but the name 'rollback' is just calling that same group by a different name? i.e, 'rollback' would be to downgrade and 'supplemental/update' would be to upgrade?

@Floob Жыл бұрын

@@AndrewHoeveler An update set will be named to say its an update set from xx.xx to version xx.xx so its relatively small. A rollback set contains all the differences from the set version back to the first version of mame (so essentially all files that have been removed or changed since the first version) - its currently about 8GB or so. A rollback set is great for rebuild exercises. So yes, it lets you downgrade. Obviously if a rom file is needed that has never appeared in the official mame releases you may need to source that elsewhere like bios files or similar, but the vast majority of files can be obtained by the latest mame set plus the latest rollback set.

Two questions. I think it was this video that you asked why would anyone ever want a merged set. Did you find out yet? Secondly, my problem is that I can find 0.243 non-merged but not the 0.243 rollback and 0.242 rollback but not the 0.242 non-merged. I do see a 0.242 merged set... Can you make a non-merged set out of a merged?

@Floob 2 жыл бұрын

Hi. Thanks for the questions. For running a merged set, I guess it would be much smaller than a non-merged, and possibly slightly smaller than a split set. Some front ends can (I think) scan a merged set and show you all the clones in it, so you can just pick the one you want. I think Mame itself and maybe Attract Mode and other can do that. But to keep things simple I tend to stick with a split set and just rip out clones in the build. But as per video, un-merged can be safest as you know any of the romsets will just work with whatever front end and emulator you use. The 0.243 rollback set is the same as the 0.242 (no changes) so you can use that. Google tends to include this in its results "0.243 rollback". Yes, I dont see why you can make a non merged from a merged set. Just use the non-merged .dat and point it to the directory with the merged in. Make sure your 'merge options' are set correctly: mamedev.emulab.it/clrmamepro/docs/htm/rebuilder.htm

@Floob 5 ай бұрын

The rebuild process will only rebuild to the xml/dat file you give it, so you could throw in all sorts of romsets (merged or otherwise) as the input, and the output will only ever match (or try to match) what your xml/dat file has. The bit at 38:00 in the video shows how to set what merge type the output romsets should be. When you download the romsets from the internet they are usually marked what type they are, I cant link but a search of "MAME 0.261 ROMs (non-merged)" should help.

The reason that one works is that it hasn't changed from a prior romset version, so its just luck really. If you rebuild, you can guarantee they will all work. I think thats what frustrates a lot of people, why some work and some dont - its because the emulator isnt expecting any new/different files for that game since the last time it was supported.

Excellent video! There is one thing I am confused about - rollback sets. I have lr-mame 0.246 and I am wanting to build the games for it. I have a merged 0.245 set and I have the 0.246 (51 zips, no chds) update. What do I need for rollback? Wouldn't the rollback be the full 0.245 set?

@Floob Жыл бұрын

If you want to rebuild to get a 0.246 set and you have 0.245 plus the update set of 0.245 to 0.246, that should be all you need. You would only need the 0.245 rollback set if you wanted to rebuild to a version that is earlier than 0.245.

@@TrevorDans The 245 set, plus the 245 rollback set (approx 9GB), yes. Together they can be used to rollback to any previous MAME version (and most variants).

Hi, thanks for your detailed video. but before any practical, can you tell me this method can also apply on full splits sets? i want to reduce the size 76 gb of full sets. but its Splits. i have checked video, in which launch box is used to reduce size,, means all clone separated and only parents left to play. its reduce more then half space. and when i tried on my full sets. most of games not worked. so i found that i have splits sets, and this method can only applicable on non-merged full sets. 1-CAN i rebuild these splits set to non merged full sets.? 2-then i will use launch box to separate clones? to reduce size of full set.? thanks ?

@Floob Жыл бұрын

I dont use Launchbox, so I cant comment on that. You can use a split set, just make sure its verified using a split set .dat file. If you are happy your split set is accurate, you can use this approach to just cut out the parent roms which should work fine: kzfaq.info/get/bejne/hNV7arZz2t63das.html The key point here is to make sure your mame romset is the same version that the emulator you are using wants.

The best starting point when you have errors in the rebuild is to expand the errors shown, and clrmamepro will explain what the problem is. For example, is it missing a given rom file entirely or is it just not happy with the version of the file you have. That info will help work out exactly whats wrong so you can find the correct file that it wants to complete the rebuild.

My retropie config developed a problem on an update, So I backed up all my romsets, config and bios. Reinstalled retropie 4.8, put the backed up folders in and now most of my arcade roms don't launch unless I config each one seperately when mame launches. I believe installing mame2003plus will fix most of this, as many of the roms are from a 2018 set.

Hi Novabug. You could use the existing MAME romsets you have if you use the same emulator (and version of emulator) that you had installed before. For example maybe mame2003-plus. If you want to rebuild your set to work against the latest version of mame2003-plus then I would download the latest rollback romset you can find and also use your existing set to rebuild.

Suggestion for two videos. If you can make a non-merged set out of a merged set, well that's one request - please show us how to do that and the second is how do these guys keep their romsets up to date i.e. how do you bring a 0.242 non-merged set up to a 0.243 non-merged set. In other words bring it up to date. They change every month I think.

@Floob 2 жыл бұрын

Making non-merged out of merged should just be a case of rebuilding it and making sure to choose the non-merged option in the rebuilder: mamedev.emulab.it/clrmamepro/docs/htm/rebuilder.htm It should let you do that as long as the .dat file has the relevant info in to rebuild that type (so choose a un-merged .dat). Yes, MAME is usually once a month: www.mamedev.org/oldrel.html To keep them up to date without downloading it all again, you use MAME "Update" sets, these just include the changes. Obviously you need to make sure the emulator you are using needs/wants these changes.
