Just a simple curiosity really .. I didn't know about the Movie Viewer 3D app until yesterday .. & it's exactly what I've been looking for .. I've not converted any films myself .. But downloaded about 40 gigs worth ... Some are louder than others . By whomever converted them ( I remember doing this type of thing in the PSP days ) .. So I was just wondering if you could make the 3ds louder with a mod app or something like that ..
