I'm probably being dense, but I've read a few of the how-to and tutorial posts.. and I still can't figure out an easy way to create gameslists of only games I actually have roms for. Its a bit annoying to scroll through 8k MAME games that I mostly don't have, but to update a custom list by hand every time I want to add a couple also doesn't seem like a good option. Sorry if this is a FAQ, but I really did try to find an answer. Saw some pointers to romdir2xml but couldn't get it to do what I wanted either.
