Its the filename(s) given in no-intros dat file. After checking md5 hashes, romcenter/clmgrpro renames the files for my collection.
Whats the purpose of a DAT files when renaming is not equivalent to the console needs?
All my stuff now gone, thanks no intro!
Most renaming tools will have various settings to allow you to customise names -- scene name, dir name, region, languages, v1/v1.1/v2, full name...
That is where I would look for fault here. If whatever string was there failed to include an extension then
Alternatively some will try to compress things and put it in a directory set in the program, been a very long time since I used either of those tools (think it was still called clrmamepro at the time) but that would be another.
Also you said gone. I don't know what that means.
From where do you have these suspicious "no intro.dat" files? Or with other words asked, what are these files? Never heard from them. I have as good as every game from nintendo's cdn and everything still works.
Blauhasenpopo already went but might as well go another.
no-intro rose to prominence mostly during the GBA era as a group that removed intros (better search term might be cracktros even if it is not accurate in this case -- the little demo animations and such that some groups put in front of a game when booting) from GBA games, compared to other ROM management tools that were more content to just catalogue things as the Scene dropped them. You might have met goodtools names in various ROM sites where you have [!] [T+Eng] and whatever else in the name for one of the other big ones

They stuck around for the DS and have since branched out into all you see on their site (
https://datomatic.nointro.org/index.php?page=download&s=46&op=dat ). Their general aim is to have the purest version of a ROM for a given system (as opposed to sliced up, compressed additionally to what devs did, intros, trainers, trimmed, scrubbed and whatever else some opt to do to their isos/ROMs). Unrelated to that but you might also find "no-intro sets" on various torrent sites which aim to be collections of such.
Today for most they also are the reference standard for ROMs used by those testing emulators, flash carts, as a base for ROM hacks and anything else.
Various members and associates also made a number of nice tools for various ROM manipulation tasks

and have one of the finest information sources on the GBA ereader

Their undumped lists are also the standard for those looking at such things
