Get US ROMs regex

This torrent contains 804 american Super Nintendo ROMs. It doesn't contain any hacks/beta's and very few doubles. A list of the ROMs is included in the torrent as a text file.

I downloaded a FULL SET torrent created by euroemu.net and used regular expressions in bash to separate the (U) ROMs from the other ones. This is the method I used:

for r in *\(*U*\)*[!].* *\(*U*\).*; do echo "$r"; done

It uses two regex's:

*(*U*)*[!].*
Gets all the verified good dumps.

*(*U*).*
Gets the other dumps that are not available as verified.

..and after that, to get rid of the hacks and beta's:

ls | grep -i -e hack -e beta | while read line; do echo "$line"; done
