Actually it's a lot easier than swapping 2 files….
To play with a mouse you'll need 30 sec by doing this :
1) Right click on the desktop to display the menu and select "Terminal Emulator"
2) Type the following command :
nano /home/stv/Voyager_Game/Run_Game
3) This will open a text file, go down to the line:
LD_PRELOAD=./stv_emu.so ./trek.e4
And add a # at the start to comment it
4) Go down 2 lines and uncomment :
LD_PRELOAD=./stv_emu_mouse.so ./trek.e4
5) Press CTRL + O then ENTER to save, and now the mouse is enable
You can repeat that for the file :
/home/stv/Voyager_Game/Run_Game_Debug
To use the mouse when in windowed version
