mame detects SF3 third strike but not new generation or 2nd impact

i downloaded all roms and chds from here at emuparadise. all roms and chds are in the mame\roms folder. i tried putting the chds in their own folders and named the folders the same as the zip files like i would for killer instinct or ki2. but to no avail.

and 3rd strike only works with the chd file directly in the roms folder. so i assume thats how their all supposed to be. but i downloaded the other 2 from here at ep and placed them just the same. and they wont detect when i run an audit.

using mame plus! plus! 0.142u5

any help would be appreciated

nevermind i got it!!! seems i just needed all of the region roms and not just the us (large) ones
