Hello,
I am using a DSi with Twilight menu (which doesn't have the seem to have dsiware equipped) ,Unlaunch, and Godmode9i. I used Godmode9i to get the DSi camera ROM or PHOTO_HNIJ01_01.nds.
when i open the PHOTO_HNIJ01_01.nds file i copied from sd:/gm9i/out i get an nds bootstrap screen saying "error has occured" also couldnt find the .pub file
i gotta say, the steam deck isn't a bad deal, even if you get a used one, you have options to get it serviced and the parts are also available through ifixit
