While working with some other stuff in the game, I keep running into certain stuff, and finally decided to create a proper launcher where you can select resolution and if it's windowed or fullscreen, and which dataset to use. With this, you can create a total conversion mod that have its own title screen and such.
The resolution/windowed/fullscreen options are working, however the dataset selection is not yet. I'll need to re-write the data loading code to work with the new launcher, but in the end, it should be a lot cleaner and less cluttered in code! As soon as I'm done with this part, I will update the Recent Build branch, maybe next week. This weekend will be a busy one for me!
Here's a screenshot of the launcher in action:
