[edit] Common container format (data.bin)
Game saves seem to be broken up into several parts. The first part is a Block that is 0xF0C0 bytes long. The 'header' seems to appear after this block, so what exactly is in this first block? One possibility is that it's the icon/banner (in a compressed form) shown in the data manager. I don't know but here's what we know about the 'header' so far...

The files seem to contain checksums and this is the reason that you can't load a modified game save. There actually seems to be multiple checksums within the same file.
The Root-CA00000001-MS0000000*-NG******** towards the end of the files might be a certificate chain, with CA00000001 being the root Nintendo certificate authority, MS0000000* being either a particular division of Nintendo, a particular manufacturer, or a particular region, and NG******** being the individual console certificate.
The folders seem follow a common naming system with 4 letters that represents
| Console type | Game name/ordinal number | Region |
|---|
[edit] Mini FAQ
[edit] Can the saves be used to execute code?
If there is a game that has a programing error then it will be possible.
[edit] Where are VC games saved?
VC games are saved in internal memory of the Wii. You can view them by clicking the Wii logo in the lower left corner of the wii menu, than clicking memory followed by Wii then channels.
[edit] Can I edit a game save?
Not until somebody figures out the chipper keys.
[edit] Is there a program to decrypt a VC game or channel yet?
Virtual Console Channels can be installed in the form of a .wad file and a wad installer.
