/title/00000001/00000002/data/setting.txt is an encrypted file containing console information.^[1]

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), however, this does not seem to correlate to how the Wii Number enumerates them.^[check]

MODEL

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

DVD

Unknown, possibly related to Disc Channel DVD icon, or to a disc drive being present?

MPCH

Unknown. Example value: 0x7FFE

CODE

The letter portion of the serial number (example "LU", "LEH")

SERNO

Serial number. Set to dummy value 98765432 for RVA.

VIDEO

NTSC or PAL.

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);
}
