due to arcade ROMs having multiple files, which often are redumped or renamed, It's already time-consuming uploading this at it is, don't count on me to do that work, you might try find those somewhere you're using retroarch, I recommend to use the split ROM set if you want the complete ROM set, but if you want a selective list of ROMs, you are better off using the Full Non-Merged Candle
Neo it's updated very often, sometimes daily, so learning how to use a ROM manager tool it's mandatory, my preferable tools are clrmamepro and romvault, rescan and rebuild the ROM set you have, and just download the new files, there is no need to download everything Arcade ROM sets are hard to maintain.
