Everybody knows that recording SC BW is a pain in the butt. Full screen causes several issues like black screen or no recording for recording programs. Recording program (e.g. Bandicam shows black screen, FRAPS lags like hell ) works perfectly if you choose the window as source. But playing in a little window never ever impressed me. Everybody knows that playing in a little window sucks ass! After experimenting with several resolutions I finally found a solution. What if I make that tiny window to look large? This guide maybe raw for now but it works very well in real. Get your ass up and execute this guide you lazy bastard .
1)Change screen resolution into 640x480 (You should change it from advanced resolutions).
2)Click into options of taskbar and select automatically hide taskbar.
3)Download and run TaskBar Hider and hide taskbar by clicking hotkey (default WIN+X). Start button and taskbar cause problems for cursor because you can't go down while playing and they are visible while StarCraft is windowed (If you don't want to run this program then optionally you can delete explorer.exe from Windows Task Manager because this causes to disappear fully everything. But I recommend this program because after recording you can show your taskbar again).
4)Launch starcraft in w-mode.
For better alignment open w-mode.ini and change WindowClientX=1 and WindowClientY=1.
You will now see that your game is running in windowed mode but in fullscreen. You can select StarCraft window with your program and record that window while playing in fullscreen windowed mode.
If the cursor goes out from window while playing just press Alt+F1 to lock it inside the window.
Recording with Bandicam: there you should select the window area, you can do it by pressing Ctrl+F when you are in the game and after clicking somewhere. That will select recording target window automatically.
If you wanna stream I suggest using Open Broadcaster Software (OBS). Right-click on the 'Sources' box and select the Window, then name it StarCraft. After you should choose StarCraft BroodWar window.
