# 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.
|
||
|
|
```

## 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.
