# 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 file (.exe), so they can be used with
free software implementations of the game engine.
```bash
==============================================================
Welcome to REWise version 0.1.0
==============================================================
Usage: rewise [OPERATION] [OPTIONS] INPUT_FILE
OPERATIONS
-x --extract OUTPUT_PATH Extract files.
-r --raw OUTPUT_PATH Extract all files in the overlay data. This does not move/rename files!
-l --list List files.
-V --verify Run 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
-p --preserve Don't delete TMP files.
-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. This will be ignored with -x or -r. It also will not try to remove TMP files, so -p won't do anything.
NOTES
- Path to directory OUTPUT_PATH and TMP_PATH should exist.
```
# State
## What can be done better
In general:
- Error handling.
- The inflate process is currently custom made with
`https://github.com/mnadareski/WiseUnpacker` as a source of information. It
is doing fine but it probably will be better and faster with a `zlib`
implementation.
Values that are currently calculated that might be in the WiseHeader,
somewhere in WiseScript.bin or a constant defined somewhere else are:
- Total inflated size
- The deflate-offset that is added to deflateStart defined in the
WiseScript.bin file.
Other values that are of interest but not found yet are:
- To determine what Wise package/version was used other then the PE build
date.
## Things that might be a problem
- REWise is only tested on Little Endian systems.
