| Block offset* | Size (Bytes) | Description |

| 0x40 | 32 | SSID of AP |
| 0x60 | 32 | SSID for WEP64 on AOSS router (each security level has its own SSID) |
| 0x80 | max 16 | WEP Key #1 (size specified in 0xE7) |
| 0x90 | max 16 | WEP Key #2 " |
| 0xA0 | max 16 | WEP Key #3 " |
| 0xB0 | max 16 | WEP Key #4 " |
| 0xC0 | 4 | IP Address |
| 0xC4 | 4 | Gateway |
| 0xC8 | 4 | Primary DNS Server |
| 0xCC | 4 | Secondary DNS Server |
| 0xD0 | 1 | Subnet mask set bit length** |
| 0xE6 | 1 | WEP mode (0: disabled, 1: 5 byte hex WEP, 2: 13 byte hex WEP, 3: 16 byte hex WEP, 5: 5 byte ascii WEP, 6: 13 byte ascii WEP, 7: 16 byte ascii WEP |
| 0xE7 | 1 | Status (0x00: normal, 0x01: AOSS, 0xFF: deleted) |
| 0xF0 | 14 | WFC User ID? |
| 0xFE | 2 | CRC16 of bytes 0x00 to 0xFD, initial value 0x0000 |
Notes:
- The IP address, gateway, DNS servers, and subnet mask length are 0 if configured for DHCP.
- Settings are based at offset 0x03FA00. Each block of settings is 0x100 bytes in size. There are three seperate blocks stored sequentially for three potential configurations.
- The subnet mask is determined by the number of set bits. A value of 0x08 would correspond to the mask 255.0.0.0. A value of 0x19 would correspond to the mask 255.255.255.128.

Notes:
- The actual location of user settings is stored in the firmware header (see the table above this one)
- Settings are written to alternating addresses: 0x03FFxx and 0x03FExx.
DS does not ask for language when RTC has been cleared except for first use.

Touchscreen calibration
The calibration settings are stored as the position of the crosshairs.
It's stored as:
u16 x1, y1; // first calibration point (top left)
u8 dx1, dy1; // corresponding pixel position
u16 x2, y2; // second calibration point (bottom right)
u8 dx2, dy2; // corresponding pixel position
See for how to read the touchscreen.
