In my opinion, using a complete romset for the 64 is overkill, those roms are too large...what I did was go over the list manually and find the english US final versions of each game (and japan roms that I know), it only takes a couple hours for me...and I think I knock the list down to about 300. Then tweaking a list of 300 isn't so bad...not to mention the HD space you can save...
