It doesn't matter where you put the INI file as long as you point GameEx at the folder it's in. It's under the MAME settings I believe. The logo goes in the logos folder, yes. It will display in your MAME menu along with, like, 4 player games, Live, Unplayed, Update List, etc. The ROMs can stay where you currently keep your MAME set. You don't need to change anything there. You're basically making a FAVORITES file/list. GameEx will know the list name for the ROM set you link up to it, so it will display altbeaj1 as "Altered Beast (Japan)" in the Games list. If you want to, you can just give me the names of the ROMs you want in the list and I can make up the INI for you.
