--- title: Wii Savegame Editing language: en layout: default created: 2008-07-23 21:31:36 +0200 updated: 2008-07-23 21:31:58 +0200 toc: false tags: - know-how - hacking - hardware - nintendo - wii --- Savegames, as well as almost all other files, are encrypted using some crypto magic. The keys were found and now there are some tools to decrypt and recrypt the savegames called [Segher's Wii.git](http://wiibrew.org/wiki/Segher's_Wii.git). To compile them, you need to also compile OpenSSL, add the `include`-directory of OpenSSL to the search path for gcc and also point the `ld` to the compiled libcrypto.a. After that, find the 3 interesting keys on [HackMii](http://hackmii.com/2008/04/keys-keys-keys/), which are `md5-blanker`, `sd-iv` and `sd-key`. Create a directory `~/.wii` and put the 3 keys in ***binary*** form in there. (No text file with the values as numbers and letters but binary files with exactly 16 Bytes per file. Use `ghex2` or such.) If everything is correct, you can uncompress savegames data.bin using `tachtig` and recompress them using `twintig`.
