Someone posted a teardown here: http://garage99.net/blog/new_3ds/

It looks like the test points aren't labeled though, compared to the old 3ds boards.

Should be these. Though it seems like it's missing a pin.
The NAND is 4GB this time btw.

....thats probaby dat0-dat3........actually those 4 points seem to all link up together once they go through the resistor array :S....blah idk :P

i guess this will be figured out eventually

Yeah those 4 looks like DAT0-DAT3. The one outside should be either CMD or CLK.

Any news on this? Would be nice to be able to got back on my N3DS LL, like I was used to on my 3DS XL. Can post pictures of my own board later, but I don't have a logic analyzer, only a multimeter.

Here are two more pics of the N3DS LL board
EDIT:
Added close-up of what I assume is the NAND chip.

Time to probe some pins with a logic analyzer I guess, I hope the CLK bus isn't on the other side of the board lol.

So this slightly interesting, the US one I have doesn't us a Samsung memory module and no epoxy resin around it either. Also the board is labbed as RED-CPU-01. Though it's highly likely it's pin compatible as everything else looks the same.

actually those 4 points seem to all link up together once they go through the resistor array

Pull ups/downs, the resistors are weak enough to force a 0 or 1 when no data is actually present but strong enough to not cause a short when the line is set to the opposite level :)

    @SylverReZ, I also heard one of the Prince of Persia games was so unfinished that it required the "24/7 online" drm so a puzzle could be done and the game could be finished. And that when the Ubisoft servers were closed the (cracked) game was impossible to finish or something like that
  • SylverReZ @ SylverReZ:
    @Xdqwerty, That's extra scummy. Ubisoft nowadays ship out incomplete games like Skull and Bones which was being worked on for nearly a decade now.

    Either that or their old games were unfinished aswell but we can't notice it

    I like that games can be fixed after the fact, hate that it's being abused via beta tests... And DLC... I was a 7800 owner back in the day and loved Impossible Mission, turns out I couldn't beat it because it was actually impossible lol
  • Psionic Roshambo @ Psionic Roshambo:
    I never knew about it at the time but a fixed version was available but you had to mail in your broken copy lol
  • Psionic Roshambo @ Psionic Roshambo:
    So that version is semi rare

    @Psionic Roshambo, I have a rom of the ds version of impossible mission
