Notes and comments

• Encryption is provided by Blowfish, a symmeteric cipher using 64-bit blocks, thus requiring the input data chunk size to be divisible by eight bytes. The retail version uses the 64-bit key { 0x72, 0x03, 0x17, 0xF4, 0x12, 0x43, 0x92, 0x88 }, and the demo { 0x23, 0x43, 0x55, 0x02, 0x37, 0x99, 0xaf, 0xc7 }.
• zlib is used for compression.
• FILETIME is a 64-bit datatype for representing time on Microsoft operating systems.
• The XBOX version of RalliSport Challenge uses the RFA format.
