Strike Witches: Silver Wing/Notes

File Formats

GGXArchive Packed Files

Most of the game's files appear to be archives created with "GGXArchiver v1.00". These can contain various types of files, including but not limited to models, textures and text. Some entries are stored as little endian

GGXArchiver Format

Entry	Format
Magic	"GGXArchiver1.00" + 0x00
Unknown (number of files? more info?)	16-bytes, ex: 0x02 0x00 0x00 0x00 0x02 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 (/media/data/sc_logo.bin) First four bytes are number of entries in the archive's file table(LE) Second four bytes are number of "valid" entries in the file table (blank entries of 32 0x00 are "invalid")(LE) Remaining 8 bytes are probably padding
File List	32-bytes per file, relative path to file, directories supported
File Headers Table	Size seems to scale with number of files in archive 0x00-0x03 NID(LE) 0x04-0x07 static 1(LE) 0x08-0x0B uncompressed file size(LE) 0x0C-0x0F Size of compressed file data in archive, probably includes compression commands(LE) 0x10-0x13 Boolean? (could also represent compression type), is data compressed(LE) 0x14-0x17 Offset from end of file headers table to start of file(LE) Repeated for each file in archive
Compression related data	See below
File Data	The actual data for each of the archived files. Appears to be have some endian weirdness, reversed every 32-bits? (Xenon is 32-bit BE, makes sense?)

Compression Information

Appears to be compressed with BPE (Byte-Pair Encoding) compression (quickbms compression method 25/55). quickbms sometimes fails decompression, may require new utility or manual decompression.
