help updating firmware/trauma center 2

I just downloaded 3.7 for my m3 ds and I need to know how to update, do I just drag the folder into my cart?Also trauma center 2 does not work, will this play on v 3.7?

no, you must drag the folder's contents onto your cart. The firmare files MUST be in the top level directory for it to work. If you are asked to overwrite files (most likely) then answer yes.

lol 3.7 firmware gets me mixed up with NDS and PSP.i have to actually read carefully.
