All you need to do is to ask :-)
Here are the 2 diffs against the latest CVS (a CVS commit which modified a
file I was working on occured when I was preparing the patch, so I don't
expect my 'latest' CVS to stay 'latest' for long :-)
You should apply safedisc-safe.diff first.
Please let me know if you need any other information.
Thanks for your help.

+SafeDisc FAQ
+
+What is SafeDisc ?
+==================
+
+SafeDisc is a CD copy protection system designed for Microsoft Windows. It is
+widely used, especially to protect games. There are currently 2 main versions
+of SafeDisc around: SafeDisc 1 and SafeDisc 2.
+
+
+Is my program protected by SafeDisc ?
+=====================================
+
+Look at the root directory of the program CD. The following files are present
+on SafeDisc 1 protected programs:
+
+secdrv.sys
+drvmgt.dll
+clcd16.dll
+clcd32.dll
+clokspl.exe
+dplayerx.dll (not present on the very first version of SafeDisc)
+
+In addition to these files, a .icd file contains the encrypted binary, while
+the main executable (usually game.exe) is only a wrapper used to load and
+decrypt the .icd file. Those two files are sometimes not stored directly in
+the root directory of the CD but only in the location of the installed
+program on your hard drive.
+
+For SafeDisc 2, only secdrv.sys and drvmgt.dll can be found on the CD. The
+encrypted binary and dplayerx.dll are now stored inside the wrapper (usually
+game.exe).
+
+
+How do I run SafeDisc protected programs with Wine ?
+====================================================
+
+If your version of SafeDisc is supported (see below), your program will run
+out-of-the-box (at least for SafeDisc related code :-) if you use NT mode
+(--winver nt40, --winver win2k or --winver winxp). Pick the version of NT that
+your program is the most likely to support (winxp with a 5 years old program
+isn't a good idea).
+
+
+How do I find out which version of SafeDisc my program uses ?
+=============================================================
+
+There is no publicaly available version numbering for SafeDisc. However, it
+seems that the version number is stored in the executable as 3 unsigned 32-bit
+integers. Using an hexadecimal editor, locate the following byte pattern in
+the wrapper (game.exe)
+
+> 426f475f 202a3930 2e302621 21202059 BoG_ *90.0&!! Y
+> 793e0000 y>..
+
+There should be 3 unsigned integers right after that, which are respectively
+the version, subversion an revision number.
+
+On some versions of SafeDisc there are 3 null integers following the pattern,
+before the version number. You'll then have to look at the 3 unsigned 32-bit
+integers right after
+
+> 426f475f 202a3930 2e302621 21202059 BoG_ *90.0&!! Y
+> 793e0000 00000000 00000000 00000000 y>..............
+
+Don't forget that the numbers are stored in little endian and in hexadecimal.
+To convert numbers stored in little endian format, invert the 4 bytes of the
+32 bits integer (e.g. 2d000000 becomes 0000002d which is 45 in decimal).
+
+So, for instance, a version of 1.35.0 (0x00000001 0x00000023 0x00000000) would
+be coded as (in hex)
+
+> 01 00 00 00 23 00 00 00 00 00 00 00
+
+For SafeDisc 1 you can alternatively check the size of the dplayerx.dll file.
+
+dplayerx.dll size SafeDisc version number
+-------------------------------------------------------
+156.160 bytes 1.11.0
+165.888 bytes 1.35.0
+172.544 bytes 1.40.4
+173.568 bytes 1.45.0
+
+Another very important information is the secdrv.sys version number, which is
+unfortunately not easy to determine. For known secdrv.sys versions, you can
+check the file size according to the table below.
+
+secdrv.sys size secdrv.sys version number
+---------------------------------------------------------
+14.304 bytes 1.3.0 (SafeDisc 1.11.0)
+14.368 bytes 1.3.0 (SafeDisc 1.35.0)
+10.848 bytes 1.3.0 (SafeDisc 1.40.4, 1.45.0)
+18.768 bytes 2.2.0 (SafeDisc 2.5.30)
+
+If you have another version of SafeDisc please contribute to these tables.
+
+
+Which version of SafeDisc are currently supported ?
+===================================================
+
+This hasn't been determined yet. SafeDisc support for Wine has been developped
+using a game protected with SafeDisc 1.35.0. SafeDisc 1.40.4 and 1.45.0 have
+been reported to work too. All SafeDisc versions which use secdrv.sys 1.3.0
+should work.
+
+Lower version of secdrv.sys might work too. SafeDisc 2 is not supported yet.
+
+
+How does SafeDisc 1 work ?
+==========================
+
+SafeDisc encrypts the real executable into a .icd file, and uses a wrapper to
+decrypt the executable.
+
+The wrapper contains 3 code sections: `.text', `.txt' and `.txt2'. `.txt' is
+encrypted.
+
+The wrapper starts by decrypting itself, using the checksum of `.text', the
+binary content of `.txt2' and some values which depend on debugger detection
+tests. If a debugger is loaded, if a software breakpoint is set in the first 8
+bytes of any of the kernel32.dll functions, or if the `.text' and `.txt2'
+sections have been modified (this includes setting a software breakpoint in
+the code), the `.txt' section won't be decrypted correctly and a crash will
+occur.
+
+On NT, the process of detecting a debugger involves loading the kernel-space
+driver secdrv.sys, which I implemented as a user-space code for Wine. On
+Windows 95, 98 or Me, it involves executing arbitrary code in ring 0 mode
+(kernel mode). This is not supported by Wine (as the underlying OS isn't as
+broken as win9x), so that's why you have to use NT mode.
+
+When the `.txt' section has been decrypted, the wrapper will then check for
+the CD key using direct SCSI operations on the CD driver. If the CD key
+doesn't match the expected value, a message box pops up to ask you to insert
+the original CD in the drive.
+
+The wrapper then loads and starts clokspl.exe for a still unknown purpose.
+
+The last stage consists in creating the game.icd in a suspended state. The
+suspended process memory is then written with some initialization code, and
+SetThreadContext is called to jump to that code. The initialization code will
+load dplayerx.dll (which is encrypted in the same way as the wrapper, with 3
+code sections), and will decrypt the main executable. Control is then
+transfered to the main executable, and the game starts.
+
+Have you ever tried to rename game.icd to game.exe, and run it ? It will
+crash, because WinMain is encrypted. It needs to be decrypted by the
+initialization code, which is found in the wrapper and in dplayerx.dll.
+
+That's pretty much all I know about SafeDisc. Don't ask me how to remove
+SafeDisc from a game. I don't know how to do so.
+
+If you have more information, especially about debugger detection and
+secdrv.sys, please let me know.
+
+
+My version of SafeDisc is not supported. What should I do ?
+===========================================================
+
+Implement support for it :-)
+
+For unsupported SafeDisc 1 versions you will probably 'only' need to implement
+the secdrv.sys that comes with your program. For SafeDisc 2 things are more
+difficult. I'm currently working on that, but please be patient.
