Hi everyone,

I'm new to this forum and have been trying to encrypt a file used in the game 'EA Sports Rugby 08'.

The file appears to be in EA BIGF format, but is likely encypted.

I had a look in hex and see that it contains several files in .viv format.

I have tried using tools such as BIGGUI and several other scripts I have tried (including the
BIG file extractor).

There are two files attached here, one is the file in .big format and a .bin file - which may be an index file of sorts.

I would appreciate any assistance with trying to decrypt this file.

The file is 90FB compressed which is some kind of Refpack (typically 10FB) compression format. Here is compressor/decompressor for it.

type decompress.exe 4bff1461263dfe7d59a840cbfd8520aa.big 4bff1461263dfe7d59a840cbfd8520aa_decompressed.big

You can extract decrypted BIGF and .viv files inside it using quickbms and this script:
