This was from sitting around and screwing with ntr.bin in IDA, for anyone curious. I repointed all the strings for paths to the end in larger buffers. Only for 3.4p2 right now, but I'm backporting to 3.2.

Xdelta files for anyone curious (don't ask for prepatched from me): https://github.com/chaoskagami/misc_3ds/tree/master/ntr_pathhack

Oh right thank you !
I'll try to see that, it should help improving again the boot time !
A big thank for this advice ! :)

It's not to improve boot time, it's to be able to load NTR files without root path clutter.

I know but for now, in order to do a selector I make a copy of the selected version with the name ntr.bin.
If I can freely put any path I can skip this copy and obviously make the boot faster ;)

This is for NTR.bin itself, and only 3.4p2 atm. It's still hardcoded into NTR.bin. But yeah, there'd be no need to perform a copy here, because it's located elsewhere.

If you apply the xdelta and pop it in a hex editor and go to the end, you'll see what I did. Every path was given 256 character buffers and relocated to the end.

I thought that this was a limitation on the ntr.bin, but didn't think of editing it.
Thanks to you I'll take a look at it (I'm a noob so it sounds really fun !!! :p).

It is. I repointered the strings to the end to fix it. ;)

It took like...six hours? @Shadowhand, I'm too lazy to look through irc logs. How long did this take?

The funny thing is that I really did do it just for the heck of it. I don't even like nor use NTR normally, so aside from 'having fun' there was no reason. ;)
