Joel16 has released what looks to be the final version of his identification app for the 3DS:
I think the time has arrived to close the doors on this project. It's been quite the 2 years and woah, the 405k downloads, that's quite the milestone for me. Thanks to everyone who were a part of this.
Both:
Now displays NAND as well as the original local friend code seed. (Useful to know if you've switched your friend code seed before)
Removed a bunch of unused functions as well as the screenshot feature. (You should be able to use Rosalina now).
Based off the latest devkitARM toolchain. Both versions are also under one branch now and can be compiled together.
CIA versions include the new boot logos by FrozenFire
Original Version:
Added some features from the GUI version - Now displays mac address for all 3 WiFi slots, card slot status and initial firmware version.
GUI Version:
Integrated 3DSident button tester. (Use start + select to activate/deactivate)
Now uses Citro2D and up-to-date tool chain functions as well as many under the hood improvements.
Slight improvements to UI to make it sort of similar to the Switch version.
