How to decrypt nds rom

[Pokemaster2001]

Umm ik this started ages ago, and I may not get a response but I wanna try anyway. I have a rom of a gb game that got to be downloadable via dsi ware (I'm just noting that cause I think that means it's a dlc thing) that I need to decrypt and ofc I have no idea how to do that.. there is no decrypted version of it (at least that I could find of, yes I searched) it was already hard af to find the file itself.. please send help

DSiWare games are not compatible with Drastic, only regular Nintendo DS games.

If you want to play DSiWare you'll need to use No$GBA on a PC as its the only emulator that does support it, and requires some extra setup for DSiWare (There are tutorials).
