3DS hack : running unsigned code in 6.3 from 4.5 (redNAND)
@smealum : / smealum http://smealum.net
it's been a while since the last video. we've been hard at work though. this video shows my booting into a 6.3 NAND image from my 4.5 3DS, and then going back to 4.5.
basically we're making the 3DS fetch its data from the SD card instead of the internal NAND flash chip. this means that we can run up to date software without having to actually update our console !
unfortunately this will not allow people with a 6.3 3DS to run unsigned code; but it will allow people with a 4.5 3DS to run unsigned code on 6.3 (and possibly later versions too).

(and before anyone points it out, yeah, this is probably the same as GW's emunand; however this was done completely independantly. took us about a week to get it working !)
(oh and the reason I'm not calling it emunand is that, in our case at least, it's not emulation, it's redirection. candidates for a name are redNAND and NAND2SD. i like redNAND.)
(and this could potentially help looking for vulns in later firmware versions, but not promising anything)
(and this also works just fine on 7.0)
