- 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.

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.

|
|
* Generate the LM (or NTLM) response from the password hash and challenge.
|
|
*
|
|
* Input: dst - Pointer to memory into which to write the response.
