Betwiin is a NAND flash conversion tool for Wii NAND images. It can re-encrypt and re-HMAC the per-console unique parts of a NAND dump from one Wii such that it will run on a second one, with the following caveats: *The version of boot1 you flash to a NAND chip must match the original one that shipped with that Wii. No exceptions. *The version of boot2 must be equal to or greated than the one most recently installed on that Wii. *No handling of bad blocks is performed; if your target NAND chip has a bad block that hits an important file required for system startup, it is suggested that you find a different donor dump to start from. ==User guide== To run Betwiin, you must have a Python interpreter and the OpenSSL library installed on your computer, along with the numpy and pycrypto modules. A computer is also required. How to use: * Copy the input dump file to the "input/flash.bin" folder. * Copy the input keys to the "input/" folder. * Copy the output keys to the "output/" folder. * Run the betwiin.py script and wait several minutes. * Retrieve the output file from the "output/flash.bin" folder and use it as needed. ==Credits== This code represented many, many hours of hard work to generate, and could not have been done without the help of segher, marcan and gray. ==External Links== * Author's website - https://hackmii.com/ * WiiBrew - https://wiibrew.org/wiki/Betwiin * Advanced tutorial - https://streamlinehd.wordpress.com/2011/05/13/betwiin-brick-repair/
