Homebrew [Release] NVRAM Flash Manager

[Rinnegatamante]

As i said here: http://gbatemp.net/threads/need-testers-for-a-cia-file.383818/
I'm working on 3DS WiFi connectivity to try to find a software mode to spoof correctly MAC address.
While doing my test, i found something that could be useful in Wifi NVRAM so i decided to make a little homebrew for this.

NVRAM Flash Manager allows you to dump and restore NVRAM flash which contains some DS Profile infos (For example you can check if your DS Profile is good for 4.1-4.5 DS Profile exploit), Mac Address (probably for TWL_FIRM only), Access Points information and other things.

When you dump your NVRAM, you get on screen also a list of your saved access points with your saved passwords so it can be useful if you forgot a password and want to recover it.

There's already ds homebrews to do this
https://github.com/WinterMute/nintendo-ds-tools
https://github.com/44670/NVReader
(forgive me, neither one can restore firmware. your tool is a helpful addition)

I'd guess those would only read in whatever's set up in ds mode anyways...

Source code?

This seems to work as advertised except it just hangs after
"dumping ..."
with no indication that the process is complete.

So this would allow us to spoof MAC addresses? (Sorry if I read wrong) A possible unban method, if Nintendo bans MACs.

Rinnegatamante already tested MAC spoofing with a banned account (setting the banned console's MAC on his non banned console, and he could still access online), so Nintendo is not banning MACs.
Or, the change he did only affects the MAC display text on screen, not the one used online. I don't know if he checked packet traffic to be sure the MAC was spoofed correctly.

As you said, MAC address i spoofed is not the real ones, NWM service is called each time you use WiFi sticker and it overwrite shared-mem saved MAC with the Wifi Adapter ones.

Manually editing MAC address used in NVRAM maybe could be used to spoof MAC for TWL_FIRM (so DS softwares) but definitively not for NATIVE_FIRM / SAFE_FIRM.

NOTE: Don't ask me 3DSX/3DS build. At this time, they CANNOT be done cause Ninjhax / Gateway don't have access to necessary services.

what about now, that we can patch stuff running via ninjhax to have arm access?
thanks for the work!

Made a new version (1.1) which solve this problem:

with no indication that the process is complete.

Also, now NVRAM Flash Manager is provided in two builds: CIA and 3DSX (Thanks to Myria for libkhax for 3DSX build).
