Johnny T Posted September 30, 2018 Share Posted September 30, 2018 Hi all, I was looking at different MAME rom sets and see that there are different types (merged, non-merged, split etc). I just wondered what people use and why? Thanks Quote Link to comment Share on other sites More sharing options...
DOS76 Posted September 30, 2018 Share Posted September 30, 2018 here is a visual aid for how the romsets work. People use different ones for different reasons. Non-Merged is mostly used by people that want to delete games out of the MAME set and only use specific games and since non-merged sets don't have dependencies like the split set it makes it perfect for that. The merged set used to not really work the best with LB but now with the recent MAME updates in LB it is a pretty good choice. So really there is little difference between using split and merged these days and non merged isn't really necessary unless you want to be able to delete things from the set without worry of breaking stuff. 5 8 Quote Link to comment Share on other sites More sharing options...
Johnny T Posted September 30, 2018 Author Share Posted September 30, 2018 Thanks @DOS76 that makes perfect sense Quote Link to comment Share on other sites More sharing options...
neil9000 Posted September 30, 2018 Share Posted September 30, 2018 Yep, i recently changed to a merged set after the MAME overhaul in Launchbox as my non-merged set was over 100GB and my new merged set is aroung 60GB, with no perceivable difference in Launchbox, all the same games work and i saved around 40GB of space. 1 1 Quote Link to comment Share on other sites More sharing options...
Johnny T Posted September 30, 2018 Author Share Posted September 30, 2018 I've currently got a "non merged" set. I mistakenly thought "non merged" and "split" were maybe the same thing as the names mean similar things. I've gone with non-merged as I wanted to put in Lord M's All Filler Mame set but it's handy to know that I can save space in the future if I need to by switching to a merged set without any detriment to the game playing experience.

Cheers Yeah monkus's no filler is designed for a non-merged set as all the roms in that set are self contained zips so dont rely on other zips to run like the other two types. As @DOS76 said if you want to handpick games out of a set or use something like the no filler bat then non-merged is what you want as its as simple as copying the game name.zip out, that is a lot more complicated with the other two set types as the game.zips also rely on other zips to run the game. 1 Quote Link to comment Share on other sites More sharing options...
Johnny T Posted September 30, 2018 Author Share Posted September 30, 2018 Yep, I think I'll stick with non-merged for that very reason, the simplicity of adding/removing games. I'm making two playlists... one will be "Every Arcade Game" and the other will be "Arcade Classics". The Classics will be Lord M's list and the other will be all the rest. I'll be able to just have a mess around in the other list and see if anything grabs my attention and then copy it over to the Classics list and build on the excellent work that Lord Monkus has done.

Yep, and monkus's bat is strictly for non-merged, if you used it on another set type you will be missing required files anyway. 1 Quote Link to comment Share on other sites More sharing options...
F.Krueger Posted January 3, 2020 Share Posted January 3, 2020 Sorry if my question is noob, but If choose to use a non-merged set for the above reasons. Do I need to make a copy of its CHDs in a folder with matching name for each Parent & Clon Zip? Quote Link to comment Share on other sites More sharing options...
Lordmonkus Posted January 3, 2020 Share Posted January 3, 2020 No, never rename any files that are part of any Mame rom set, this is the same for the regular roms and CHDs. Mame looks for the file names as they are and as long as you either put the CHDs in the same folder as your roms or tell Mame where the CHDs are located it will find them and use them. 1 Quote Link to comment Share on other sites More sharing options...
DOS76 Posted January 3, 2020 Share Posted January 3, 2020 No a merged CHD set will work properly with a non-merged rom set 1 Quote Link to comment Share on other sites More sharing options...

vaderag Posted August 25, 2021 Share Posted August 25, 2021 (edited) So, I recently decided to move from a merged to a non-merged setup and starting afresh to try and get an all killer setup I have the latest Mame executable and rom set (234) but when I run Mame sf2 (for example) I get a whole bunch of 'not found' errors (presumably because those files are in separate archives. How do I stop this? Secondary question - is there an All Filler batch or similar for later versions - seem to only find for 17x Edited August 25, 2021 by vaderag Quote Link to comment Share on other sites More sharing options...

Secondary question - is there an All Filler batch or similar for later versions - seem to only find for 17x The whole point of non-merged is that files are NOT spread around in other zips, each zip file is complete working game, hence the size difference in the sets, non-merged contains thousands of duplicate files. My guess though is you simply haven't told the emulator your rom path, so it can't find any of your games, it looks in MAME/roms by default, so if your roms are not in that emulators folder you need to specify were they actually are.

Yeah, sorry getting confused due to the not working... Anyway, it seems to be due to me using multiple rom paths... if i remove the second it works... Any ideas why the following doesnt work? rompath "I:\CLEAN ARCADE SETUP\Roms\MAME 0.234 ROMs (non-merged)"; "I:\CLEAN ARCADE SETUP\Roms\MAME 0.232 CHDs (merged)" Oddly the files it was looking for weren't in the SF2 zip which added to the confusion, but as I say, removing the second directory name works Quote Link to comment Share on other sites More sharing options...

Added the space to try fix - didn't have the space to start The following still breaks rompath "I:\CLEAN ARCADE SETUP\Roms\MAME 0.234 ROMs (non-merged)";"I:\CLEAN ARCADE SETUP\Roms\MAME 0.232 CHDs (merged)" But the following works rompath "I:\CLEAN ARCADE SETUP\Roms\MAME 0.234 ROMs (non-merged)" EDIT: Okay, so I've tried directory renames, etc and there is no way to put multiple rom paths in here. Maybe it's a 234 bug, maybe it's something odd with my machine, but only one rom path will work... Edited August 26, 2021 by vaderag Quote Link to comment Share on other sites More sharing options...

Not per path like yours: rompath "H:\Roms\Arcade Classics;H:\Roms\Sammy Atomiswave;H:\Roms\Sega Model 2;H:\Roms\Sega Model 3;H:\Roms\Sega Naomi;H:\Roms\Sega Hikaru;H:\Roms\Sega Naomi 2;H:\Roms\Sega SystemSP;E:\LaunchBox\Emulators\Arcade Classics\_Mame_Bios" I added the rom paths via the Mame configuration menu, not by editing mame.ini. (I also use Mame 0.234 and no problem Mame recognizing the rom paths.) 2 Quote Link to comment Share on other sites More sharing options...

Not each individual path. rompath "I:\CLEAN ARCADE SETUP\Roms\MAME 0.234 ROMs (non-merged);I:\CLEAN ARCADE SETUP\Roms\MAME 0.232 CHDs (merged)" 1 Quote Link to comment Share on other sites More sharing options...
vaderag Posted August 26, 2021 Share Posted August 26, 2021 Thanks guys - that did the trick! Assumed the quotes were for the path with spaces ala the command prompt 1 Quote Link to comment Share on other sites More sharing options...
