Hi, I've seen a lot of thread asking if it was possible to run DS games on 3DS with the use of a DS linker, from the menu, like a DSiware eshop app or GBA ambassador VC. here's what I stumbled upon today : https://en.m.wikipedia.org/wiki/Advance_Wars:_Days_of_Ruin A Japanese release was announced under the title of Famicom Wars DS: Ushinawareta Hikari(ファミコンウォーズDS 失われた光?), but was canceled after several delays. However, on October 30, 2013, it became available in Japan through Club Nintendo as a downloadable platinum status reward for the Nintendo 3DS system. I then thought, maybe it's a DSi compatible game so they did a DSiware special release... but I checked and the game came out before the DSi was out. (also thr game is too big for the hardcodded biggest DSi size) some more info https://m.reddit.com/r/3DS/comments/1piu6f/advance_wars_days_of_ruin_is_the_first_nintendo/ Maybe there's a size limit but I think games that are the same size or smaller than this could also work.. Btw, the same thing just happened again with the my nintendo reward program and WarioWare Touched is available for japanese 3DS. (I really hope someone will dump it and experiement with it) So there it is. What do you guys think? And sorry if this has been brought up before. did anyone ever dumped the cia and extracted it?
