https://github.com/meladroit/ootsdhax_installer Ignore the fact that it's named ootsdhax_installer ... I want to make it (clarification: the save file, not the installer) read the payload off the SD card, but don't really have time to make it work. (It's either that or compressing the payload like ironhax does.) I can't really provide support for this, and probably won't keep developing this, so please fork it away and keep working on it ... Additionally: yeah, this is doable with just the save manager, but I figure this streamlines getting ahold of the right payload for your FW (basically by pinching ironhax installer code) and the right save file for your region (prebuilt from smea's oot3dhax fork). Also additionally: http://gbatemp.net/threads/ironhax-youtubehax-free-homebrew.393975/page-213#post-5646192 (a similar thing as this that I somehow missed) works only for USA 9.9, so I wonder if this only works for 9.9 as well. This definitely works on both USA O3DS and JPN N3DS (both 9.9), though, so can somebody on EUR check this out? Just curious. Some updates: Here's a tutorial by someone actually helpful. The installer seems to work for 9.9 for all regions, but possibly not 9.0-9.2. Getting the latest boot.3dsx may fix some problems. ninjhax1 support is not really something on the horizon, since it would require recompiling the payload with otherapp support, which is a bit of a pain. Since I'm entirely on 9.9, I'm afraid I also wouldn't be able to test it properly. Hopefully a more competent dev can help people out there.
