sorry if I add here but I have a simple question for Retroarch: I created with clrmamepro the correct romset for the Current-Mame version (currently 0.250) but when I scan the folder with the room with the option “import content” I do not see any rom in the Playlist. What am I wrong? I’m going to be crazy. I cerate a “split-romset” When I used COre and romset version 2003 -plus no problem instead
If you have your DAT from clrmamepro, don’t use RetroArch’s own database scanner. Instead, use a manual scan and then feed it the DAT you created. This will bring in all of the games and give them their proper names (i.e., instead of sf2.zip or whatever)

wowowow!!!
Is there a guide I can follow for these operations? “Manually scan and use my DAT file in retroarch”. Usually I use the .exe of the MAME with clrmamepro, not the dat file, because I always do not know which one to select… (example below)
GREAAATTT!!! Thanks I figured out how to do it! tnx tnx tnx

This is really interesting; so it looks like under: Import Content, Manual Scan and then Arcade DAT file, you can scan a directory and Retroarch will use the DAT selected to display the title from the specific DAT?
@retrogaming yes, this is how you create playlists with arcade romsets, read the section about playlist support from the arcade documentation for more information.

Thanks @BarbuDreadMon 
Do you know what DAT RetroArch will use if you do not provide one?
I’m assuming it would use the latest DAT that matches the installed Core?
I found what appears to be the DATs here https://github.com/libretro/libretro-database/tree/master/dat
Afaik it won’t use any dat if you don’t choose one.
