Thank you very much for the extensive and illustrative response, it helped me to understand how everything works. What you say makes sense, and analyzing the content of the .zip would take too much time... Exactly, one of those 5 games is PONG. Curiously, the PONG (which LaunchBox lists, and locates in MAME_ROMS\pong.zip), does not exist in the .dat nor does it appear in the complete non-merged romset folder. I don't understand why LaunchBox adds it. But it solves it later when scanning for deleted roms. There it does detect it and eliminate it. I have enough space on my drive, so I think I'm going to keep the "non-merged" version, because it's the closest thing to any console romset (1 file = 1 game, regardless of whether it's a hack, a clone , and so).

Well, I've downloaded the non-merged ROMSET from the same site as the merged romset (a 100% reliable website) and the results are much better this time. When I use the "Scan for removed roms" option, now I only get 5 ROMs, when with the merged romset it appeared that there were 1826 extra to remove. I think this is a LaunchBox problem. LB should handle romsets the same whether they are merged, non-merged or split, I believe.

Thanks for the quick reply. MAME releases updates every month that add ROMS, but also remove them, or rename them. Between the last version and the second to last, after deleting/moving files, about 90 new ROMS were required to be downloaded. Most were adjustments to existing ROMS. That is, if I understand you correctly, if I download the "full" version instead of the "merged" version, would these problems disappear or would they be minimized?

Hello, I'm having problems with the latest version of LaunchBox, a version that I installed fresh. First, when I imported the games through the "MAME Arcade Full Set" option I selected the "Skip tabletop games" option, but despite that, It imported chess games, which LaunchBox cannot identify (for example, Addometer Calculator and Chess Companion). Anyway, the biggest of my problems is something else. When I added the games the way I told you (Import>MAME Arcade Full Set), I received a total of 3078 games (full ROMSET 0.262) with my selection of preferences when importing the games. The next thing was to select the "Scan for removed roms" option. I received a notice that 1826 ROMS were being removed. I hit OK. Next, I hit "Scan for added roms" (NOT from Import>ROM Files) and 2906 new ROMS appeared. After accepting, right now I have 5829, and ALL of them are duplicates, as you can see in the screenshot. I know that if you choose the "Import ROM files" option and select "Force importing duplicate games" the ROMS will be duplicated. But that has not happened. I have only scanned for added roms. As you can see in the following screenshots, it seems that it considers the ROMS as if they were different, despite being exactly the same and being in the same folder. Thanks. EDIT I've started again installing flesh LaunchBox, trying to replicate the problem. If I import all the ROMs using the "MAME Arcade Full Set" option, It shows me 3078 games. Now, If I choose "Scan for added roms", it show ZERO (0) roms. Now, If I choose "Scan for removed roms", it shows 1826 roms to delete (why? These roms exists in the correct folder). I choose DELETE, but now, I've 3000 games (3078-1826 is not 3000...). Now, I scan for added roms: 0 new roms. EDIT 2 I've selected ALL ROMS and deleted all them (Displaying 0 of total 0 games). Tools>Scan for added roms. "No additional roms were found".............. EDIT 3 Now, I've added ALL roms using the "MAME Arcade Full Set" option, without any Skips. In the preview I see again 3078 games (impossible, it is a bug), but at the end of the process, the real number is 19825. OK. I choose again "Scan for added roms", it show ZERO (0) roms. Now, I choose "Scan for removed roms", it shows 11489 roms to delete. After removing, I can see at the top: Displaying 14376 games. I'm going to test it with Nintendo 64 ROMS...
