nsuds

Compiling the game on a Raspberry Pi

The display was initially weird and the game was not playable; I had to add the signed keyword in two locations:

In the file called gen.c:

extern signed char grid_data[9][9];

and in the file called nsuds.c:

signed char grid_data[9][9]={{0}}; /* grid_data[y/row][x/col] */
