/shared2/sys/SYSCONF
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.
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.
Types
| Name | Value | Size | Note |
|---|---|---|---|
| BIGARRAY | 1 | varies | 2 bytes of length, followed by $n bytes of data
|
| SMALLARRAY | 2 | varies | 1 byte of length, followed by $n bytes of data
|
| BYTE | 3 | 1 byte | |
| SHORT | 4 | 2 bytes | |
| LONG | 5 | 4 bytes | |
| LONGLONG | 6 | 8 bytes | |
| BOOL | 7 | 1 byte | 0 is false, anything else is true (most commonly 1)
|
Note that both BIGARRAY and SMALLARRAY store the length minus one in the beginning. A length of 0x06 means that 7 bytes of data follow. The name "ARRAY" need not indicate the actual content type; most settings store an application defined structure in them.
