In the example mod, there is file in the gfx folder named "titleback.png", it just replaces the regular main menu background animation.
For my mod Im using my own png file, however... the original background is shown on top of my new, but shrinked in size. I thought I will replace my own titleback through the example file just for testing, the same result.
So anyone got an idea what to do? (Maybe changing some screen file, but what one and how, I have no idea about this desktopx stuff or whatever is used)
