PAC (File Format)
From Wexos's Wiki
PAC files are found in /Data/flash/data_jp from Mario Kart Arcade GP DX's filesystem and they contain layout and image data.
File Format
The file byte order is always little endian.
File Header
The file starts with a header that is 0x14 bytes long.
| Offset | Type | Description |
|---|---|---|
| 0x00 | Char[4] | File magic. Always pack in ASCII. |
| 0x04 | Int32 | Number of files. |
| 0x08 | Int32 | Offset to String Pool, relative to the end of the File Entry List. |
| 0x0C | Int32 | Alignment used before file data. Always 0x20. |
| 0x10 | Int32 | File type:
|
| 0x14 | End of header, start of File Entry List | |
File Entry List
After the header, there's an entry list with entries for each file. Each entry is 0x10 bytes long.
| Offset | Type | Description |
|---|---|---|
| 0x00 | UInt32 | Unknown. Seems to be some kind of hash of the real file name. Strings are assigned to each file in the String Pool, but they do not contain an extension. |
| 0x04 | Int32 | Offset to file's string, relative to the start of the String Pool. |
| 0x08 | Int32 | Offset to file data, relative to the end of the entry list. |
| 0x0C | Int32 | File length. |
Followed by the last entry, the data is aligned from the header alignment.
String Pool
At the end of the file, after the file data, there's a string pool, which contains null-terminated strings linked to each file.
