The SYSCONF contains many Wii system settings.
The format of the file is fairly simple. Its size is 0x4000, and it contains a header that reads "SCv0", followed by the number of settings in the file (be u16), and then a list of offsets of each setting (be u16). Each setting (aka "Item") contains first a u8, specifying the type of the value, and the length of the name. The low-order 5 bits specify the length of the name, minus one. The high-order three bits specify the type of the value, as given by the table below. This is followed by a name, in ASCII, then a value. In the case of a BIGARRAY, the value begins with a be u16 specifying the length of the data, in bytes, which follows. In the case of a SMALLARRAY, the value begins with a u8 specifying the length.
Last 4 bytes of the file read "SCed".
Conventions for adding or removing settings to the file are currently unknown, but shouldn't be too hard to determine--although that's not necessarily a useful function.

| IPL.SADR | BIGARRAY | 0x1007 | lots | "Simple Address" Contains some region info |
| IPL.CB | LONG | 4 | ?? | Counter Bias -- difference between RTC and local time, in seconds |
| IPL.PC | SMALLARRAY | 0x50 | string | Parental Control password/setting |
| IPL.CD | BOOL | 1 | bool | Config Done flag -- has initial setup been performed? |
