# Linux D2Loader v0.02b (any Diablo version) by hifi (Toni Spets)
# additional fixes by Merl
#
# ChangeLog
# v0.02b - Added Merl's fixes for slow computers:
#           call Game.exe instead Diablo II.exe
#           wait n seconds before linking back the original Game.exe
#
#          removed that stupid loop when using dualhead
#
# v0.01  - Initial release
#
# Howto use:
#  0. Install Wine (http://www.winehq.com)
#  1. Install Diablo 2 with Wine
#  1b. Optional: Update to Lord of Destruction
#  2. Patch to v1.11b
#  3. Go to your Diablo 2 directory
#  3. Rename Game.exe to Game.exe.orig
#  4. Download fixed Game.exe from e.g. GameBurnWorld
#  5. Rename the fixed Game.exe to Game.exe.crk
#  6. Make sure all paths and options below are correct
#  7. Run this script and pray
#

#!/bin/bash

GAME="Warcraft 3"

# Diablo 2 options
D2PATH="$HOME/.wine/drive_c/Program Files/Warcraft III/"
D2OPTIONS="-opengl"
# uncomment to enable
#D2OPTIONS="-skiptobnet"
EXE=war3.exe

# if the script fails because you have a slow computer, increase this value to wait up before linking back to the original Game.exe
SLEEP_SECONDS=2

# dualhead hack (running windowed mode [see winecfg] with lower resolution)
