Don't leave commented out code like that.
It appears that clearScreen() has become redundant, as in both STATE_TITLE and STATE_GAME the whole screen area gets repainted with drawBackground() anyway, so we can safely remove this call from the code.
But how does it fix tearing on your platform?

Bittboy does not have vsync and apparently the screen is being cleared directly after clearScreen() call. This is a probable reason of black horizontal bars showing in random positions on the screen. After removing that call, screen tearing is not visible to that extent and becomes acceptable (at least for me). Lack of vsync is a known issue on Bittboy.

Move this change to the previous commit, as it is unrelated to the tearing fix.

There is no need to include a default game config, as the game will generate one on the fly if it doesn't find an existing one.
The same goes about the default score file.

I had some issues with those and got Segmentation Fault on Bittboy. Not sure if it was the reason as I made other changes as well, but for completeness I have put defaults in there. Feel free to remove them.
Makefile changes and minor screen drawing tweak to avoid screen tearing on Bittboy, it should not affect other platforms.
