Jump to navigationJump to search

PTCL (ParTiCLe) is a file format used on the Nintendo Switch. It contains visual effects, made from emitters, models and textures. It also may contain shader data.

File Format

Header

The file format starts with the following header:

Offset Type Description
0x00 Char[8] File magic. Always VFXB in ASCII, or 56 46 58 42 20 20 20 20.
0x08 UInt32 Version number.
0x0C UInt16 Byte-order-mark. FE FF for big endian, FF FE for little endian.
0x0E Byte Alignment shift. 2 raised by this value is the alignment required by this file when loaded into memory.
0x0F Byte Target address size. Size of a pointer in bits, thus 64.
0x10 UInt32 File name offset. The offset links to 0 bytes, which probably explains the 0x20 empty bytes after the header.
0x14 UInt16 A flag which is only used on runtime. One bit sets wether the file is relocated. It is unknown if this is used to indicate whether the embedded files are relocated.
0x16 UInt16 Offset to the first section.
0x18 UInt32 Relocation table offset. Since PTCL files don't have a relocation table, this is always 0.
0x1C UInt32 Size of the file in bytes.

Section Header

Every section starts with the following section header. All offsets are relative to the start of the section, and may be 0xFFFFFFFF if unused. It has the following structure:

Offset Type Description

0x10 UInt32 Sub data offset.
0x14 UInt32 Image offset. By default it is set to the size of this structure.
0x18 UInt32 Unique ID. Unknown usage, always 0. The IDs seem to be generated at runtime.
0x1C UInt16 Number of childs.
0x1E Byte Flipped flag. Set at runtime if the file endianness doesn't match the system endianness, and all values need to be flipped.
0x1F Byte Endianness flag. Determines the endianness of this structure, 0 for little endian, 1 is big endian.
