 Fix for the game "Itsuka Furu Yuki" (it.exe / itufuru.exe)
 Indeo Video 5 (IV50) decoder installer
========================================================================

WHY THIS IS NEEDED
------------------
The game crashes (or closes immediately) on some computers because its
intro/OP movies are encoded with an old codec called "Indeo Video 5"
(fourcc IV50). Modern Windows does not include this codec anymore.
This package adds the original 32-bit Indeo 5 decoder (ir50_32.dll),
so the game can play its movies again in full original quality.

WHAT'S IN THIS FOLDER
---------------------
  ir50_32.dll   - the decoder itself (small video codec file)
  install.bat   - one-click installer for the decoder
  README.txt    - this file

HOW TO INSTALL
--------------
1. Copy the whole "Indeo5_fix" folder anywhere on the computer
   (Downloads, Desktop, a USB stick - it does not matter).
   IMPORTANT: keep install.bat and ir50_32.dll in the SAME folder.

2. Right-click on "install.bat" and choose
   "Run as administrator".
   (If Windows asks "Do you want to allow this app to make changes?" -
   click "Yes".)

3. A black window will appear. Wait a few seconds, then press any key.
   That's it - the codec is installed.

4. Start the game as you normally do. The OP movie should play now.

NOTES
-----
- Nothing needs to be copied into the game's folder.
- The game can be installed on ANY drive/folder - the installer works
  the same way for everyone.
- Works on Windows XP / Vista / 7 / 8 / 10 / 11, both 32-bit and 64-bit.

IF THE GAME STILL CRASHES
-------------------------
- Make sure you ran install.bat "as administrator" (without this,
  the codec is not installed).
- This fix solves the video codec crash ONLY. If the game still closes
  with a text/Japanese-locale error, install a Japanese locale emulator
  like "Locale Emulator" (for itufuru.exe) and launch the game through it.

HOW TO REMOVE THIS FIX (IF EVER NEEDED)
---------------------------------------
  reg delete "HKLM\SOFTWARE\WOW6432Node\Microsoft\Windows NT\CurrentVersion\Drivers32" /v vidc.IV50 /f
  del %SystemRoot%\SysWOW64\ir50_32.dll
