tl;dr We can send any ds demo to the (3)DS(i) using a modded wbfs. ALSO, we CANNOT send homebrew, only officially signed demos. So don't even ask. This is a project that is fairly simple in concept: replacing a .srl(DS download rom) with another to basically have access to all demos(nintendo channel, ds download station, etc.) from the original DS. Yet, as simple as this may seem, I found ZERO mention of this anywhere else. None. At. All. So, I got to work. Here's the video I made showing this off: (Yes, this has been around for a while, as seen by the upload date. Kinda forgot about it for awhile ) So, with that out of the way, here is a rundown of what is happening: We load up a .wbfs with the custom .srl(brain age demo) on the Wii, which will begin broadcasting this out. Now, here is why I think this is so unrecognized: 1) Not too much purpose 2) There are only about 10 games capable with sending .srl files to a ds. PBR actually just so happens to send a .srl to Diamond/pearl(NOT Platinum or HGSS, as seen here), and this seems to be the most stable game to do this with. So, onto how to do this: YOU NEED: 1) A homebrew'd (v)Wii 2) 2 (3)DS(i)s 3) 2 Gen IV pkmn games, one of which must be Diamond or Pearl. 1) Download the inject.zip from the attachments 2) Get a PBR wbfs and name it input.wbfs 3) Get a ds demo and name it input.srl 4) Run inject.bat and wait 5) Copy output.wbfs to the (v)Wii. Run it, start up a ds battle, and connect both pkmn games. When it's done, you should have the demo on the ds with Diamond or Pearl.
