    I recently modded my N3DS XL from a 4-pin JST to a 6-pin MicroJST,All DAT lines except DAT3 is being used, I also notice slow read speeds of about 2.1Mbp/s I should be getting 5.5Mbp/s, Im using a Transcend TS-RDP8K

    I've checked for any touching wires but none, I get the default Bootrom error 200, each wire is coloured coded for, Black(GND), Red(CLK), Yellow(CMD), Green(DAT0), Blue(DAT1), White(DAT2)

    Is your makeshift SD missing the lock switch?
    If its missing, it won't push the contacts together in the SD reader and enable writing...

    Also, your pictures are broken... use a different host... like imgur.

    And I also think that you either use ALL DATs, or only DAT0, don't skip DAT3.

    And, as above, if the small piece is missing, it's the same as being READ only. Put some tape around the FrankenSD to ilude it.

    Its soldered directly to the sd card port with a switch to toggle the write, I have fixed this by soldering to the MicroSD port , requires a dud MicroSD to be inserted

    You can get 5.5mbs with 4 wires...

    You need the other dat soldered as well if using the 7 wire install. Check your ground.

    I'll just de solder the Dat1 and Dat2, from the SD card reader, do I have to do it on 3DS side?
