Make sure that your game is running on the correct resolution, otherwise problems may occur.

You can change the resolution pass some parameters to the shortcut of the game.If you have not made​​ a shortcut to the game,create it with any text editor by following the rules bellow.

 Supported parameters

-w Starts the game in windowed mode
-r Change the game resolution

 How to use? 

Open the shortcut file and insert the following:

#/ bin /bash
cd "path to the folder of your game"
(wine SC3.EXE -r1024x768)

The example above starts the game in fullscreen and with resolution 1024x768

Another example:

#/ bin /bash
cd "path to the folder of your game"
(wine SC3.EXE -w -r800x600)

The example above starts the game in window with resolution 800x600.

 Supported Resolutions

640x480, 800x600, 1024x768, 1280x1024

 Note: if you uses multicore cpu, read tutorial Fix Multicore Freezing / crashing (below)

 Install with: # apt-get install schetool

Or:

$ wget http://freequaos.host.sk/schedtool/schedtool-1.1.2.tar.bz2
$ tar xf schedtool-1.1.2.tar.bz2
$ cd schedt*
$ sudo make install

run sc3k by:
$ schedtool -a 0x1 -e wine SC3.EXE

 NOTE: If you use different resolution and multicore, use this model of shortcut:
#/ bin /bash
cd "path to the folder of your game"
(schedtool -a 0x1 -e wine SC3.EXE -r1024x768)
for more information read the tutorial Resolution (above)

To resolve those two problems:

1) Open the wine directory (~/.wine or your wineprefix) and delete all .reg files.

2) Download and replace you wine to wine 1.3.29.

3) In terminal run wineboot command.

3) Play and enjoy ;)
