Made some major changes...

Now decodes the code sections correctly from both HackMii and Datel

-----

Not sure if anyone cares but this is a bit of PHP to show, decrypt and output the Wii Letterbomb payload.
Edit the file with your MAC address and filename or just use the one I've supplied.

It will show you what goes where inside the binary and how things are decoded.

Might be best to show the source code, upload it to GitHub or something. Might just be me, but I am always skeptical of forum attachments when it involves hacks/payloads.

Sorry don't have a github account or anything...
If you download it , make sure to unpack it with 7-Zip or something else safe...
Zip contains two files, one made on Hackmii and the other is just PHP code, very easy to read and understand.

Nah I understand, it is more than likely a safe archive, but there will be others more skeptical than me who may want to use this but choose not to. GitHub is free to sign up for, if you plan to release more projects, it'd be in your best interest to host them there. Just a tip! :)

Nice post title :D
Just for curiosity, are there other layers of obfuscation left on the hackmii installer?

Have a look at the output file and you'll see that everything is plain.

The file is encrypted using the key in the header and the actual code is encrypted with a 32bit xor for Hackmii and 8bit xor for Datel.

It will even tell you where the sections are just incase you wish to rebuild or create your own.

    The snack that smiles back, Ballsack!
  • TwoSpikedHands @ TwoSpikedHands:
    I really would like to make a hack that I would enjoy playing, and maybe other people would too. swapping to the EU version would also mean my US friends could not legally play it
  • TwoSpikedHands @ TwoSpikedHands:
    I am definitely considering porting over some of the EU features without using the actual ROM itself, tbh that would probably be the best way to go about it... but i'm sad that the voice acting is so.... not good on the US version. May not be a way around that though
  • TwoSpikedHands @ TwoSpikedHands:
    I appreciate the insight!
  • The Real Jdbye @ The Real Jdbye:
    @TwoSpikedHands just switch, all the knowledge you learned still applies and most of the code and assets should be the same anyway
  • The Real Jdbye @ The Real Jdbye:
    and realistically they wouldn't

    be able to play it legally anyway since they need a ROM and they probably don't have the means to dump it themselves
  • The Real Jdbye @ The Real Jdbye:
    why the shit does the shitbox randomly insert newlines in my messages
  • Veho @ Veho:
    It does that when I edit a post.
  • Veho @ Veho:
    It inserts a newline in a random spot.
  • The Real Jdbye @ The Real Jdbye:
    never had that i don't think
  • Karma177 @ Karma177:
    do y'all think having an sd card that has a write speed of 700kb/s is a bad idea?
    trying to restore emunand rn but it's taking ages... (also when I finished the first time hekate decided to delete all my fucking files :wacko:)
  • The Real Jdbye @ The Real Jdbye:
    @Karma177 that sd card is 100% faulty so yes, its a bad idea
  • The Real Jdbye @ The Real Jdbye:
    even the slowest non-sdhc sd cards are a few MB/s

  • Karma177 @ Karma177:
    @The Real Jdbye it hasn't given me any error trying to write things on it so I don't really think it's faulty (pasted 40/50gb+ folders and no write errors)
  • DinohScene @ DinohScene:
    run h2testw on it

  • DinohScene @ DinohScene:
    when SD cards/microSD write speeds drop below a meg a sec, they're usually on the verge of dying

  • Psionic Roshambo @ Psionic Roshambo:
    Samsung SD format can sometimes fix them too
  • Purple_Heart @ Purple_Heart:
    yes looks like an faulty sd
  • Purple_Heart @ Purple_Heart:
    @Psionic Roshambo i may try that with my dead sd cards

  • Psionic Roshambo @ Psionic Roshambo:
    It's always worth a shot

    @The Real Jdbye, I considered that, but i'll have to wait until i can get the eu version in the mail lol
