That may be okay for yourself but its standard practice on all the major arcade emulators , the console dumps do not change .
The benefit of using the same console dumps comes out in support as issues can arise between dumps , for instance an emulator can be known tp play a verified USA dump but may have issues with the same games release from Europe .Its about consistency.
The next release will be very large for the full set and all it takes will be for the original uploader to make a dat of the set and if they release by torrent to torrentzip the roms. Than anyone wanting to download the set runs a dat over there current stuff and matches what they can ,next they have to start than stop the torrent ,copy the matched items to the roms folder and torrentzip it for consistency to the original uploaders files and away they go.
The torrent will fix any missing or changed drivers within any arcade rom and the whole thing saves everyone a shitload of bandwidth
