dborth 65984b9102 [What Was New 004 - August 5, 2008]
- added: option to disable AA filtering 
         (snes graphics 'crisper', AA now default OFF)
- added: mapped zooming and turbo mode to classic controller
- added: preliminary usb support (loading)
- changed: sram and freezes now saved by filename, not internal romname. 
           If you have multiple versions of the same game, you can now have 
           srams and freezes for each version. A prompt to convert to the 
           new naming is provided for sram only.
- changed: by default, autoload/save sram and freeze enabled

*
* Notes:
*
* This module implements the LM hash. The NT hash is simply the MD4() of
* the password, so we don't need a separate implementation of that. This
* module also implements the LM response, which can be combined with the
* NT hash to produce the NTLM response.
*
* This implementation was created based on the description in my own book.
* The book description was, in turn, written after studying many existing
* examples in various documentation. Jeremy Allison and Andrew Tridgell
* deserve lots of credit for having figured out the secrets of Lan Manager
* authentication many years ago.
*
* See:
* Implementing CIFS - the Common Internet File System
* by your truly. ISBN 0-13-047116-X, Prentice Hall PTR., August 2003
* Section 15.3, in particular.

/* -------------------------------------------------------------------------- **
* Functions:
*/
uchar *auth_LMhash( uchar *dst, const uchar *pwd, const int pwdlen );
/* ------------------------------------------------------------------------ **
* Generate an LM Hash from the input password.
*
* Input: dst - Pointer to a location to which to write the LM Hash.
* Requires 16 bytes minimum.
* pwd - Source password. Should be in OEM charset (extended
* ASCII) format in all upper-case, but this
* implementation doesn't really care. See the notes
* below.
* pwdlen - Length, in bytes, of the password. Normally, this
* will be strlen( pwd ).
*
* Output: Pointer to the resulting LM hash (same as <dst>).
*
* Notes: This function does not convert the input password to upper
* case. The upper-case conversion should be done before the
* password gets this far. DOS codepage handling and such
* should be taken into consideration. Rather than attempt to
* work out all those details here, the function assumes that
* the password is in the correct form before it reaches this
* point.
*
* ------------------------------------------------------------------------ **
*/
uchar *auth_LMresponse( uchar *dst, const uchar *hash, const uchar *challenge );
/* ------------------------------------------------------------------------ **
* Generate the LM (or NTLM) response from the password hash and challenge.
*
* Input: dst - Pointer to memory into which to write the response.
* Must have 24 bytes available.
* hash - Pointer to the 16-byte password hash.
* challenge - Pointer to the 8-byte challenge.
*
* Output: A pointer to the 24-byte response (same as <dst>).
*
* Notes: The function does not check the lengths of the input or output
* parameters. The byte sizes given above must be respected by
* calling function.
