Exporting MAME Roms from LB

[The Papaw]

Can you export MAME roms from a Merged set like you can with a non-merged set. Like shown in last youtube video? Going to build a new setup using 0.273 and need to be able to export them for NAS. I do use chd files as well if that matters

Depends.  If your main ROM file (default game) is the parent ROM, then yes.  If it's a clone (located inside the parent ROM zip file [in a merged set]), then no.  

i.e.  path/to/1942.zip (parent ROM)  vs.  path/to/1942b.zip (clone ROM) 

In a merged set, 1942b.zip does not physically exist.  But that's the [non-existent] filename that gets pointed to.  (and it works [plays], because MAME is smart and knows how to handle it)

 

Note: "Only the main ROM files will be copied and not any additional applications."

Regarding exporting, it does matter. Regardless of the set.  A lot.  

Again. "Only the main ROM files will be copied..".   When imported, the path to the 'game' is (i.e.)   path/to/area51.zip.  It will export that [Parent] ROM.  But it won't touch the other required path/to/area51/area51.chd

Thanks Teach, so I should probably use non-merged set to import into LB, then export them to be added to NAS to save HDD space on NAS. Less chances of them not working and less headache, other than time. Would you agree? BTW, hope all is well with ya Joe

Not sure if this falls under a double entendre or an oxymoron.   

Merged          - (0.273) 76.54 GB
Non-Merged - (0.273) 141.6 GB

That is course is for the Full set(s) and you'd only be exporting some of those.  So "to save space.."?  In the end.. Probably not.  To have the export feature [more so] work in-your-favor and "Less chances of them not working and less headache"? Most likely.
