PNEL is a file format that is used by Puzzle Swap of StreetPass Mii Plaza for loading additional puzzles to the 7 default ones. PNEL probably stands for Panel.
File Format
Header
| Offset | Size | Description |
|---|---|---|
| 0x00 | 0x04 | Magic word "PNEL" |
| 0x04 | 0x04 | Magic word "0800". Probably last 4 digits of the japanese title ID. |
| 0x08 | 0x04 | Number of puzzles |
| 0x0C | 0x04 | Unknown. Always 0x00000001 |
| 0x10 | 0x04 | CRC-32 over the 0x14 bytes of the header with this field being 0. |
After the header the first additional puzzle begins.
Puzzle Entry
| Offset | Size | Description |
|---|---|---|
| 0x00 | 0x04 | Order number. First puzzle is a 7 because 0-6 are the preinstalled puzzles |
| 0x04 | 0x04 | CRC-32 over the 0xC30 bytes of the puzzle entry with this field beeing 0. |
| 0x08 | 0x04 | Absolut offset of start of puzzle image |
| 0x0C | 0x04 | Absolut offset of start of puzzle settings |
| 0x10 | 0x04 | Absolut offset of start of puzzle model/figure |
| 0x14 | 0x04 | Size of puzzle image |
| 0x18 | 0x04 | Size of puzzle settings |
| 0x1C | 0x04 | Size of puzzle model/figure |
| 0x20 | 0x04 | CRC-32 over data of the puzzle image |
| 0x24 | 0x04 | CRC-32 over data of the puzzle settings |
| 0x28 | 0x04 | CRC-32 over data of the puzzle model/figure |
| 0x2C | 0xC00 | Name of the puzzle in different languages |
| 0xC2C | 0x01 | ID of number of puzzle pieces: 0 => 15 pieces; 1 => 24 pieces; 2 => 40 pieces |
| 0xC2D | 0x01 | Pink puzzle pieces |
| 0xC2E | 0x02 | Unknown or Padding |
The data of the image, settings and model/figure are always padded at the end with 0x00 until size is divisible by 4 (4 byte alignment). These padding bytes are not part of the CRC-32 calculation
