Whats New/Fixed:
- Calculates "normal" game save signatures. That is, signatures which were generated using the normal, non-no-roam signature calculation algorithm (HMAC-SHA1).
- Calculates "no-roam" game save signatures. That is, signatures which were generated such that the data would only be valid on the original XBox that it was saved on (uses the XBox's unique hard drive key).
- Calculates many secondary "custom" signatures and CRCs. That is, signatures and CRCs in which the manufacturer of the game used their own custom algorithms to generate secondary signatures, CRCs, etc.
- Supports game saves which use multiple signatures.
- Supports game saves which store their signatures in a separate file from their data.
- Uses INI files for maximum flexability.
- API-like resigning routines for easy integration into other applications. (see "Attention Developers" section)
