Changing splash screens
BNSBoost allows changing of splash screens, and randomly picks an enabled splash when starting the game. Splashes are stored in %appdata%/BNSBoost/splash, and accessible from the UI under the "Splash" tab.
To add a splash screen, click the Open splash folder button, and copy your splash image into it. Then, Refresh splash list, and finally check the box next to your splash. A random splash screen from those enabled will be applied when you click Launch!
Natively, the game supports only BMP-formatted splash screens. BNSBoost offers support for splash screens in other formats (PNG, JPG, etc.), which are converted on-the-fly to BMP for when the game needs them.
