Voting for ROMs

Are we supposed to rate the GAME and how fun it was, or the quality of the dump or something?

There really is no "quality" of a dump, as every copy is the exact same, and is not compressed or modified in any way. You rate the game itself and how fun it is.

Ok, thanks! ;)

I'll specify that in the text explaining how to rate a game. As a ROM site admin I find it obvious though, it can be hard to put myself in a users place sometimes.
