Well, I saw @shinyquagsire23's repo and was wondering what it could do. Then I saw some of his posts about being able to at least read from the Gateway SD card from k9lh, but not necessarily more, so that's why I ask. Would it be possible to redirect all SD read/writes to the Gateway micro SD? What would be the point? Well, nothing too exciting, but still not so bad: give a use to the Gateway card some people here bought BEFORE free CFWs become an actual thing (so people who come here to say "Gateway is useless, get a free CFW" clearly missed the whole point because that's exactly what I'm saying) allow New 3DS users to have their micro SD card in a slot that isn't behind two screws (I hear "Filezilla" in the background. You mean that thing that requires a WiFi network and that corrupts JKSM saves?) maybe support exFat, depending on how the whole thing works, assuming it even works have something else than dust in the cartridge port (yeah, I'm trying hard to find arguments ) Note, I'm not even asking for people to do it, just at least if it's doable.
