You would have to delete and readd the DAT as a whole you're building to change these options. You can answer each one individually if you want to see what games it's referring to and tailor it for each game. It's really a preference and it may work even (14 years since 0.37b5 was released a correct dump might exist) but I still stick with 'No to all'. It found a checksum for a ROM that matches and it may or may not work but MAME is telling you there is no known good dump and do you want to use it. Insert found checksum instead of using the 'nodump'? Issue: Possible wrong nodump definition found.Ī valid checksum for it within its parent/clone relationship was found though. a DAT file you'll get prompted with some questions. If I remember right it's less than 6 games roughly. I think the creator of MAME4ALL added a few more games to the DAT but no major/popular games were added. There's some very minor differences between the DAT built from the official executable and the one included in the zip.
MAME 0.139 ROMSET LIST ZIP
If you already have the DAT which has one included in the MAME4ALL for the Raspberry Pi zip you don't need the executable. You would download the mame.exe from under the 'Previous Releases' section. If you don't want to use a pre-built DAT you can create your own too: MAME doesn't care which version you use and you'll end up with a different number of files and space use depending on how you parse your files but all 3 methods work for MAME. The pic above really helps illustrate how they work. If you only want a 2-player version of a game but the master is a 4-player version. The advantage is good use of space the disadvantage is you have to always need the master game ROM even if it's not a version you want. In this format it's not uncommon to only have 1 or 2 ROMs in the clone or bootleg.

When you download sets they are usually in this format where the master ROM set holds the common ROMs and the clones and bootlegs only hold the additional needed ROMs to run that game. Split Sets are in the middle so to speak. The disadvantage is you end up with several versions of Donkey Kong that you don't necessarily want. The advantage is it's easy to get the correct game like for Donkey Kong you grab dkong.zip and it will work. Merged sets create the fewest files as each zip has all the master, clones, bootlegs, etc. The drawback is it takes a while to parse the files and uses quite a bit more space. The advantage is you can get the exact game version you're looking for like Defender red label, white label, etc.
MAME 0.139 ROMSET LIST ZIP FILE
Non-merged sets use the most space and the most files because each zip file is a standalone game ROM that can work in MAME. I don't know if this would help but it helped me quite a bit having a visual:
