I just got started using GameEx and wow its awesome and it was a breeze to setup compared with what I had been using. I have read different suggestions on how to sort out games, and I was curious which route to take. I have a full set and obviously don't want to scroll through all of them to find the game I want to play. I thought about just using the favorites, and I also seen where people said to just create a custom rom folder for just gameex that contains only the games I want to play. So what's the recommended way to do this? What works best? Are there other alternatives? Thanks!
