Sometimes you'll also see (M3) on the filename as well, such as 4522_-_The_Legend_of_Zelda_Spirit_Tracks_(E)(M5)(XMS)
4522 = Release number
(E) = Region, European in this case
(XMS) = Release group
(M5) = Multi-language, in this case it has 5 different languages available to choose from
Also, please do remember that this site is not for asking for ROMS or providing them either. Google really goes a long way for that.
