    At least you don't need ASM all THAT much ... but it does have it's uses.
    Most stuff can be done just fine in C.

    I've been wondering, I haven't seen the Trinux thread on Gbatemp updated in some time. Has any progress been made behind the scenes?

    Forgot to post this here but I added a download section to the googlecode page
    http://gbadev.googlecode.com/
    (now that google has taken away the normal option for a download tab, that was a bit of a pain TBH)
    with a little teaser alpha release. It contains
    1. the ppcboot.elf file for the current Linux kernel (sorry, no 3-core yet ... but at least it can reset the console properly on a Wii U now)
    2. the ELF forwarder boot.dol to run it (needed to run ANYTHING you would run normally through BootMii on a normal Wii ... so just switch out the ppcboot.elf for something else if you like)
    3. the WAD for the BootMii IOS (since HackMii doesn't install BootMii IOS on Wii U, I packed mine into a WAD ... at least until we can get things running smoothly without it.)

    I'll eventually get around to updating the OP with this, hopefully.

    I've added a "miscellaneous tools" section to the download page on the googlecode site.
    as usual, here's the link to the site https://code.google.com/p/gbadev/

    This is for tools I've had to code up in the investigation process, trying to figure out how things work.

    So far, I've only added a ancast image decrypter but more to come.
    for information about an ancast image, go here : http://wiiubrew.org/wiki/Ancast_Image

    Basically, it's what Nintendo uses to store some of those things that have an extra layer of encryption on Wii U like the System Menu and the NANDLoaders (the things that look like IOS512 and IOS513) so this would be the tool to use if you're curious about their contents.

    The way you use it:
    1. You extract the downloaded ZIP file onto the SD card
    2. You get the right(*) APP file for the title you're interested in our of a NAND dump rename it to 00000017.app and place it in the bootmii folder on the SD card
    3. Run the "launch bootmii" option from HBC
    4. The Wii U hardware will decrypt the encrypted portion of the file, dump it into sd:/bootmii/dump.bin and then reset the console back to the Wii U menu.

    (*) the right APP file, depending on which one you're interested in is :
    00000003.app for the 1-512 title
    00000001.app for the 1-513 title
    0000000c.app for the OLD system menu
    00000017.app for the NEW system menu (after this last 4.0 update)

    If you think it's taking too long, to check on it's progress take a look at the sensor bar with a digital camera. The LED's will turn on while it's decrypting so before that it's still loading and after that it's dumping it to the file.

    enjoy

    What about the whole /dev/flash chat you guys had @ GBAtemp? Did you actually get to something? Or is it something planned to do with Trinux at a later time?

    I was thinking about modifying the current RealWnD source to access the NAND registers under PPC... I *think* I can do it, taking the nand.c file from the MINI git repository and the NAND registers page from Wiibrew as a starting point, considering the read8/16/32 functions from libogc have access to this particular area.

    I apologize if this post is somewhat off-topic.

    No, I don't think that's off topic at all, we can use all the help we can get

    I don't really see how NAND dumping can help to improve the Trinux development... I was just asking if anyone was able to do something about it.

    Just an update, sven from f0f offered to help if the Trinux team (meaning Maxternal) had trouble on a specific issue.
