yes i use attract mode and it's fairly easy creating "romlist" and adding the info for games is what i think you are referring too but you can use hyperspin xml's to generate your game list and there is also a couple sites for mame games that gives you all the info regarding players,year,genre e.t.c but for games like taito type x just use hyperspin.xml for that system and point the directory to that file to generate it i hope this helps buddy
check out this link to better help you learn how it's done
