Correct me if I’m wrong here because its been a few weeks, but isn’t the name of games handled by the gamelist.xml? The scraper does indeed pull metadata from the roms hash and uses that to generate the gamelist file. If you edit this file for the specific console you can change things.
I for example was too lazy to run the scraper myself to avoid wrong naming of roms. I instead just let it auto-run and then corrected the errors myself by editing the gamelist file. You can name the rom whatever you would like in there. You can also easily correct improper images and what not. This was simpler/quicker for me than individually scrapping thousands of games.
Floobs video will help you scrap info for MAME and pifba! I actually used his method myself. Same thing applies to mame with the gamelist.
