    Select a valid memory range, yeah. Use the kernel address table to pick one of the first ones because they're assembly regions.

    Yes!

    I don't really understand why we need to load the modified mocha though.
    Other apps can read from sd without using this modified version, so why does tcpgecko need it?
    And after loading mocha, I can't use directly open the hb channel?
    I have haxchi installed, I'm not really sure how else to get into the hb channel without loading it from the home menu, without using the web exploit but for 5.5.2 it's annoying to use.
    I don't know anything about the mii maker method, I have had my wii u for less than a week :D

    Anyway, this is great new thank you for all the work everyone involved.

    Because it doesn't have permissions to do it anywhere like when you load arbitrary titles.

    Oh because tcpgecko is running in the background when we want it to load codes from the sd card, and it needs higher permissions - I get it :)

    A future idea could be to, load tcpgecko/cheat app, select the cheats we want - these are loaded into ram from the sd card (within the app, so no modified mocha needed)
    Start the game, and the codes are already there.

    If we can get this sd card access patch added to haxchi, that would be great too.
    I'm not so sure how viable that is, @FIX94 is that something that would be accepted in your haxchi?

    As far as I remember he already said that he won't add this into haxchi/CBHC (read pages 1-2 of the FSHax thread)

    It's not a stability question, you can read the FSHax thread (it's about "permissions" and such)

    Please help me! I installed all of the necessary files on the SD card and put it in my wii u. Then I installed and ran JGecko U. It did not auto detect the wii U, so I put in the wii U IP address. However, it comes up with an error page every time I click connect.
