Daigasso Band Brothers Expansion

Can you use the Daigasso Band Brothers expansion on a EZ-Flash 3 in 1? Is it just a GBA rom or something I could flash to NOR RAM?(If you can, links please. :p )

As when you copy things to NOR ram it acts permanently does it not? If this is the case then unless the NDS game can tell when its not the official cartridge I see no reason for this not too work.I cant be certain though.
