Fields

All fields are stored in the format KEY=value on separate lines.

AREA

This seems to correlate to the system menu region (The letter that appears after the system menu version), enumerated in the following way:^[check]

Japan ("J") = 0,^[2]
USA ("U") = 1,^[3]
Europe ("E") = 2,^[4]
Korea ("K") = 3^[5]

MODEL

The RVL-xxx model. Set to RVL-001 for vWii.

CODE

Some internal console-unique number

SERNO

Serial number

VIDEO

NTSC or PAL video mode

GAME

Another region, possibly set by rgnsel?

Encryption

setting.txt is encrypted by the following symmetric algorithm:

unsigned int key = 0x73B5DBFA;
int i, len;

if (is_enc)
{
	len = 256;
} else {
	len = strlen(buf);
}

for(i = 0; i < len; i++)
{
	buf_ptr[i] ^= key & 0xff;
	key = (key << 1) | (key >> 31);
}
