mame wont see both rom folders

Im using a port of mame0.78 on an xbox360 (RGH), it works well but there is a folder size limit on the xbox file system, i split the roms into two folders, roms and roms2, i have edited the mame.ini with what ever i could think of to get it to see both folders, it only see the first roms folder, i tried putting roms2 folder in roms folder and renaming it roms, still no joy...

the default dirs are...

RomsPath0 = game:\roms
RomsPath1 = usb0:\roms
RomsPath2 = usb1:\roms
RomsPath3 = hdd1:\roms

ive tried...

adding another path RomsPath4 = hdd1:\roms2........... didnt work

RomsPath3 = hdd1:\roms;roms2

currently the ini looks like this..

RomsPath0 = game:\roms
RomsPath1 = usb0:\roms
RomsPath2 = usb1:\roms
RomsPath3 = hdd1:\roms;roms2
RomsPath4 = hdd1:\roms2
RomsPath5 = hdd1:\emulators\MAME\roms2

Still it wont see roms2

This is the folder structure on the xbox..
