/*
* C version of the 'space' assembly demo.
*
* Little demo illustrating how to use the graphical possibilities
* of the GB (background, window and animated sprite)
* I have used fixed-point values for both the position and
* speed of objects to get smooth movements
*
* OBJ data : 0x8000 -> 0x8FFF (unsigned)
* Window data : 0x8800 -> 0x97FF (unsigned)
* Background data : 0x8800 -> 0x97FF (signed)
*
* Tiled 0xFC -> 0xFF are standard tiles (all black -> all white)
*
* Keys:
* Arrow keys : Change the speed (and direction) of the sprite
* Arrow keys + A : Change the speed (and direction) of the window
* Arrow keys + B : Change the speed (and direction) of the background
* START : Open/close the door
* SELECT : Basic fading effect
*
* Note that the window is kept in the lower right part of the screen
* since it can't be made transparent
