Is there any site that lets you download a file that contains

There are a surprising amount of fullsets curated directly by archive.org but they are fucking BIG so please make a note of it.

There's several MAME torrents ranging from 5-50GB. Choose your poison

I'd guess you could probably find a torrent, but they'd be literally 10s of gigs.

>>3980330
Yes

Pleasuredome has a good set.

So I downloaded Haunted Castle version M but Mame tells me that I'm missing one rom or chd file.

The problem with doing it this way is that they put every version of a particular ROM known to man for every game so you have to weed through the hacked and bad ROMS.

MAME Protip:
Got a ROM .zip that MAME just will not run? Wondering what files you are missing to cause this problem? Open a command line and navigate to where your mame.exe or mame64.exe is. Then type in mame(64).exe nameofgame.zip MAME will attempt to run the game, crash, and in the command window it will show you what files it was expecting to see. Download those, move them to your rom directory, and play.

You want MERGED set. Files are bigger, but it has all variants and hacks in the same .zip as the base game to prevent clutter.
