# 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

# Diablo 2 options
D2PATH="$HOME/.wine/drive_c/Diablo II"
# uncomment to enable
#D2OPTIONS="-skiptobnet"
GAME_EXE_ORIG=Game.exe.orig
GAME_EXE_CRACKED=Game.exe.crk
# you can find fixed exe for D2:LoD 1.11b from GameBurnWorld (cracked by DEViANCE)

# wine and system options (e.g. wine or cvswine)
WINE=wine
# 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)
DUALHEAD=1

# dualhead xrandr options
NATIVE_RES=0
GAME_RES=0

## ACHTUNG!
# remove the line below when you have configured this script (it's actually harmless but makes you sweat alot ;-)
