I was wondering if there is a graphical tool that allows you to select certain games from a dat file and recreate a new dat with only the selected games. I want to give MAME4driod a try which is based off of v0.37b5, but I only want to put a couple dozen of my favorites on my tablet. I'd prefer not to have to rebuild the entire 0.37b5 set from the current set and would like to select & rebuild only those games I'm interested in. I realize I'll need to find the roms that are no longer included in the current set.
