Press the Start button to begin.

The object of the game is to remove tiles to score points.  To remove tiles you
must build horizontal or vertical lines of three tiles or more.  You build lines
by swapping two tiles horizontally or vertically such that one or both of
the swapped tiles will create a line of three or more tiles.  These  lines
will disappear and the tiles above will fall with new tiles filling in
from the top.  If the falling tiles come to rest in such a way that new lines
are created, these lines will disappear and more tiles will fall until the board
has no more lines.  You can only swap tiles if it will create a line, other swaps
are not allowed.  The game ends when there are no more moves (the cursor will
disappear).  Once the game ends you can press both shoulder buttons at the same
time to reset the GBA and start again.

The binary jewel008.bin does not have a valid header, just zeros as a placeholder.
It is compiled for 0x8000000 (cartridge).

I dont suppose there are extra points for the header and the program to be less than
4096 bytes?
