Reverse Engineering Wise
Extract files from Wise installers without executing them.
The aim of this project is to extract assets from old game installers made with Wise installer without executing the PE/NE file (.exe), so they can be used with free software implementations of the game engine.
==============================================================
Welcome to REWise version 0.3.0-debug
==============================================================
Usage: rewise OPERATION [OPTIONS] INPUT_FILE
OPERATIONS
-x --extract OUTPUT_PATH Extract files.
-r --raw OUTPUT_PATH Extract all files in the overlay data. Filename format will be 'EXTRACTED_%09u'.
-l --list List files.
-V --verify Run extract without actually outputting files, crc32s will be checked.
-0 --raw-verify Run raw extract without actually outputting files, crc32s will be checked.
-z --script-debug Print parsed WiseScript.bin
-v --version Print version and exit.
-h --help Display this HELP.
OPTIONS (--list)
-e --extended Also print languages and components.
OPTIONS (--extract, --list, --verify)
-f --filter FILTER Filter files based on their filepath. Multiple of these filters may be set. '*' will match anything, use '\*' to escape.
-F --file-filter FILTER_FILE Path to a file that contains one filter string per line.
-c --components NAME Filter files by components name. Note that default files are always included.
-g --language INDEX Filter files by language index. Note that default files are always included.
OPTIONS (any)
-p --preserve Don't delete WiseScript.bin from TMP_PATH.
-t --tmp-path TMP_PATH Set temporary path, default: /tmp/
-d --debug Print debug info.
-s --silent Be silent, don't print anything.
-n --no-extract Don't extract anything. Use WiseScript.bin at the given TMP_PATH, it won't delete it.
NOTES
- Path to directory OUTPUT_PATH and TMP_PATH should exist and be writable.
- All files REWise does output will be overwritten when they exist!

Acknowledgement
The WiseUnpacker project kick started this project by giving insight on how to inflate files from Wise installers. So a lot of thanks to mnadareski!
REWise is different in that it tries to understand and proper parse the
WiseScript.bin, not everything is understood yet but it looks
like most of that is relevant is.
Technical
NOTE: The PE build date will not be the same as the installer creation date (or release date) since the overlay-data is just appended to a existing Wise PE32 stub on creation of the installer. The supported installer release dates seen so far are between 1999 and 2003. While the PE build dates are between 1998 and 2001. NE files do not contain a build date.
A Wise installer is a PE or NE executable with extra data appended to the end of
it (overlay-data at the overlay-offset). The overlay-data contains a Wise specific
header. After the Wise header there is raw DEFLATEd data without file-headers,
after each DEFLATEd data entry there is a CRC32 for the inflated data. The
DEFLATEd data + CRC32 continues until EOF. Unless the installer is created
with the zip support option, then before each DEFLATE data there is a zip
local file header, and there is no CRC32 after the DEFLATE data since it is
in the zip local file header.
The first inflated file is a .dib file we call WiseColors.dib, containing
colors used by the installer, it is no use for us so we skip it.
The second inflated file is a binary file that has all sorts of data relevant
for the installation (including custom file headers). Within REWise this file
is named WiseScript.bin. Most time was spend on reverse engineering
different WiseScript.bin files with a hex-editor (ImHex) so a
WiseScript.bin can be parsed without as much of guessing as possible. One
discovered struct that is the most relevant for extracting files that would be
installed by the installer is (it contains file names, metadata, CRC32 and
offset to deflatedata):
/* 0x00 WiseScriptFileHeader */
typedef struct {
unsigned char unknown_2[2]; // seen: 0x8000, 0x8100, 0x0000, 0x9800 0xA100
uint32_t deflateStart;
uint32_t deflateEnd;
uint16_t date;
uint16_t time;
uint32_t inflatedSize;
unsigned char unknown_20[20]; // 20 * \0?
uint32_t crc32; // do not check when it is 0
char * destFile; // \0 terminated string
char * fileText[langCount]; // \0 terminated string(s)
unsigned char terminator; // always \0? terminator?
} WiseScriptFileHeader;
On how REWise handles a WiseScript.bin file: SEE src/wisescript.h and
src/wisescript.c.
PE build dates
NOTE: Stubs are patched on creation of the installer so we cannot do a sum of
compiledinstallers and compare below.VsVersionInfoandStringFileInfoare patched and a value in a section somewhere up is patched to contain the overlay offset value.

Shareware
A large collection of Wise installers is used to test REWise, see tests/extended/results/README.md for the current stats. A list of all the installer sources can be found here.
Known issues
- The
ScriptDeflateOffsetisn't correct on some installers, there are still some unknowns on how to calculate this proper. - WiseScript
OP 0x18is not understood. - The code used to get the language/comp per file still has unknowns, therefore not all installers will work, but most do.
- Installers where the inflated file size is larger then advertised, these will not work because REWise is strict about the advertised inflate size.
- Installers that have weird extra bytes in the WiseScriptHeader.
- Multi file/disc installers are current not supported.
To determine what Wise package/version was used other then the PE build date. However it looks like there is none, but: On Wikipedia is a list of different Wise installer releases, comparing that list to the tested installers (games) their PE build date it suggests that the targeted Wise installer versions are either one of these:
- WISE Installation System version 7 (1998) (InstallMaker)
- WISE Installation System version 7 (1998) (InstallMaster)
- WISE Installation System version 8 (1999) (InstallBuilder)
- WISE Installation System version 8 (1999) (InstallMaker)
- WISE Installation System version 8 (1999) (InstallMaster)
- WISE Installation System version 9 (2001)
Multi-disc installers
All multi-disc installers are current NOT supported.
A workaround is to append the .W02, .W03, etc.. to the setup.exe
to make it work with REWise. Example:
cat setup.exe setup.W02 setup.W03 > new_setup.exe
| PE BUILD | FILENAME | NAME |
|---|---|---|
| 25-04-2000 16:37:12 | setup.exe | Hitman Contracts (2004) |
| 25-10-2001 21:47:11 | Gothic2-Setup.exe | Gothic II (2003) |
GOTHIC II
Would be nice to support for the use with REGoth-bs or OpenGothic.
Other things that might be a problem
- REWise is only tested on Little Endian systems.
- Wise installers where the PE was build before 1998 or after 2001, or installers that where created/released before 1999 or after 2004.

Many thanks to
- The WiseUnpacker project for a great source of information.
- The FragNet community for testing and feedback.
- Archive.org, cd.textfiles.com and discmaster.textfiles.com, without them all the shareware installers would not have found.
