Hi,
GonzoBrian said right.
But using the multiconf_wizard , you don't have to much control on game lists generated. List are based on INI file and you can not remove one specific game from the list. (or you can do that by editing generated file with the notepad).
If you plan to have only one list (no multiconf) , it is better to do that using AtomicManager.
On the Advanced Tab , you check "use predefined gamelist" AND check "let Atomic choose file names" , then go on the "GAME LIST" tab that appears, and build your list as you want.
You can as well build your list by putting games one by ones or using automatic category transfert.
