         **************************************************************

This is a patch that fixes many issues introduced in the US version of the PC 
Engine CD/TurboGrafx-CD game Exile (Japanese title: "Exile: Toki no Hasama he") 
by its publisher, Working Designs. The US version makes the game more difficult 
by increasing enemy stats, removing the "Warp" spell, and altering the contents 
of some treasure chests. This patch restores the gameplay from the original 
Japanese game.

              ****************************************************
              *                     Changes                      *
              ****************************************************

* All enemies have their stats restored to what they were in the Japanese 
version.
* The "Warp" spell that returns Sadler to the start of the current dungeon has 
been re-enabled.
* The two chests in the game that contain gold have been restored to their 
original amounts (900g -> 500g, 2000g -> 2500g).

Other changes in the US version (the dubbing, the obfuscated real-world 
locations, the horrible horrible made-up script) have been kept.

For specific details on the alterations in the US version, such as tables of 
stat changes and so on, see this page (which I may or may not have written yet):

              *               Patching Instructions              *
              ****************************************************

--- WHAT YOU'LL NEED ---
* A BIN/CUE or ISO/WAV format disc image of the US version of Exile (PC Engine 
CD/TurboGrafx-16).
* If you're on Windows, the xdelta patching utility (http://xdelta.org/) is 
provided in this distribution. On other platforms, you'll need to acquire 
version 3.0.8 or later on your own.

--- AUTOMATIC PATCHING METHOD (WINDOWS) ---

If you're using Windows, move your disc image files into the same directory as 
the program and do one of these as appropriate:
  * If you have a BIN/CUE disc image, drag and drop the BIN file (or IMG file) 
onto binpatch.bat.
  * If you have an ISO/WAV disc image, drag and drop the ISO file onto 
isopatch.bat. Note that your ISO/WAV files must use standard naming and 
numbering, e.g. "File 01.wav", "File 02.iso", etc.

If everything works, this should produce the patched game under the name 
"ExileUnWorked_##". To play it, make sure the file "ExileUnWorked.cue" (included 
with the patch) is in the same directory as everything else and then load it in 
an emulator, or burn it to a CD for use on real hardware.

If this doesn't work, try using the manual patching method below to diagnose the 
problem.

--- MANUAL PATCHING METHOD---

--- CONVERTING FROM BIN/CUE TO ISO ---
If you have a BIN/CUE image (or the equivalent IMG/CUE), you'll need to convert 
it to ISO/WAV before you can patch it. I'd recommend using BinChunker (a.k.a. 
bchunk -- homepage http://he.fi/bchunk/) to do this.

* On Windows, you can use the included bchunk.exe (courtesy of elmer). If you 
don't want to use bchunk, there are also many "shareware"/commercial utilities 
that can do this task, though they may or may not output the same ISO as bchunk.
* On Linux, it should be available from your distro's repos, or of course you 
can build from source.
* On Mac, you can build from source, or perhaps get binaries wherever Mac people 
get their binaries from.

To convert, open a command prompt and navigate to the folder containing the 
BIN/CUE, then run the following command:

bchunk -w ExileUS.bin ExileUS.cue ExileUS_

(substituting the names of your BIN/CUE files, obviously -- remember to put 
quotes around them if they have spaces in them. **Don't rename them** -- this 
will cause the conversion to fail unless you also modify the CUE file itself.) 
This should generate a series of files: ExileUS_01.wav, ExileUS_02.iso, 
ExileUS_03.wav, ExileUS_04.wav, and so on up to ExileUS_38.wav.

--- PATCHING STEPS---
1. First, !!!***verify that your ISO has the correct MD5 hash***!!! It should be 
c8f0c632555306cc9bd7235cb078b5c8. If it isn't, the patch almost certainly won't 
work. You can obtain this by using the md5sum utility on *nix, or the FCIV 
utility (https://support.microsoft.com/en-us/kb/889768) on Windows.

2. Use xdelta to apply ExileUnWorked.xdelta to your ISO. If you're using the 
command line, this would look something like:

xdelta3 -d -s ExileUnWorked.xdelta ExileUS_02.iso ExileUnWorked_02.iso

If you use a GUI wrapper, it should be self-explanatory, but make sure the 
output file is named ExileUnWorked_02.iso.

3. Verify that the patched ISO has an MD5 hash of 
a6e71fd37587e8d336835a57233c3699.

4. That's technically all the patching required, but assuming you want to play 
on an emulator, we now need to make sure the CD audio files are properly 
associated with the ISO or it will likely hang when it needs to play them. 
First, make sure your patched ISO is named ExileUnWorked_02.iso, then rename the 
audio files produced from the BIN/CUE conversion process to 
ExileUnWorked_01.wav, ExileUnWorked_03.wav, etc.

5. A CUE file named ExileUnWorked.cue is included with this patch. Move it to 
the same directory as your ISO and WAV files.

6. Test that the game works by loading ExileUnWorked.cue in your emulator.

--- TROUBLESHOOTING ---
* If the patched ISO won't run, check the MD5 hashes of your original ISO and 
the patched ISO. The correct hashes are given in the steps above. If either of 
them doesn't match, try a different method for converting the BIN/CUE to ISO, or 
using a BIN/CUE generated by a different program.
* If your ISO has associated sound files in some format other than WAV (or your 
emulator doesn't support WAV files), you'll need to either convert them to WAV 
or modify the CUE file to use a different format. In the latter case, change 
(for example) all occurences of WAVE to MP3, and make sure the filenames are 
correct.
* If the game works fine but crashes when CD audio should play, your audio files 
aren't properly associated with the ISO. Check that your filenames match what's 
described in ExileUnWorked.cue.
