Rsizetable

The resource size table is an ares file format managed by ares::ResourceSizeTable. It contains an array of sorted file path Crc32b hashes + file resource heap size pairs, the earliest revision has no header. Since succeeded by a version with a 0xc byte header and an optional additional array of fixed 128 byte file paths + file resource heap size pairs for file paths that would produce a hash collision. Since succeeded by version with a new 0x16 byte header, the 0x6 byte magic makes all subsequent u32 values unaligned.

Header (revision 1)

Offset	Size	Type	Description
0x0	0x4	u32	Magic ("RSTB" in big-endian)
0x4	0x4	u32	Crc32b resource size pair count
0x8	0x4	u32	Path resource size pair count

Header (revision 2)

Offset	Size	Type	Description
0x0	0x6	u32	Magic ("RESTBL" in big-endian)
0x6	0x4	u32	Version?
0xa	0x4	u32	Reserved
0xe	0x4	u32	Crc32b resource size pair count
0x12	0x4	u32	Path resource size pair count

Crc32b Array

Array of hash + size pairs immediately following the header, if the header exists. Sorted by hash.

Offset	Size	Type	Description
0x0	0x4	u32	Crc32b of 128-byte file path
0x4	0x4	u32	Size required by file resource in ares

Path Array

Array of path + size pairs immediately following the Crc32b array, if the file path array exists. Sorted by path.

Offset	Size	Type	Description
0x0	0x80	const char[0x80]	128-byte file path
0x80	0x4	u32	Size required by file resource in ares
