MAME Samples not loading on RG353V

[Sideburn]

I cannot get samples to load on my RG353V does anyone know where the heck the correct path is?
I have tried:

/samples
/mame2003/samples
/mame/samples
/mame/mame2003/samples
/mame2003-plus/samples
/bios/mame2003-plus/samples
/bios/mame2010/samples
/bios/mame2003/samples

It can vary between emulators and also the game you are playing as some games load different MAME version or FBNeo.
Try
roms/bios/mame2003-plus/samples
roms/bios/fbneo/samples folders
