So i was exploring the different options in GodMod9 when i had my DSTWO inserted and i selected the gamecart option. when i clicked it, it shows two files: ALEX RIDER_ALXX78_00.nds and ALEX RIDER_ALXX78_00.trim.nds. in theory, if those are the files that mandate which game icon gets shown when the cart is inserted, can you change which game you want shown, or even customize with new banners inside that NDS file? or will there be complications if that is a specially coded ROM? Just throwing out a theory and maybe someone better suited can explain more, or even attempt this?
