mame games not loading

hello all i have a softmodded xbox with MAMEdOX_1.1_FULL_080305 and it is showing all the roms for the path i have set for it and they show up but when i go to load the game it states rom file missing and goes back to main dashboard for the roms what do i have to do or change for this to work right thanks ahead for all reply's

p.s. all roms are there and loaded

im not to sure about this but maybe u need the neogeo bios and cps1 and cps2 bios i use kawax on my xbox and i have the bios in the roms folder

You're missing some ROMs for that MAME version, perhaps BIOS like NeoGeo (there's no CPS1-1/2 BIOS) or maybe the ROM sets there doesn't match with this MAME.

ok well when it says missing rom files its cuz the bios arent in the xbox i jus tryed it without bios
