Well, this sprite would normally be defined by:
table[25]={
1,0,0,0,1,
0,1,0,1,0,
0,0,1,0,0,
0,1,0,1,0,
1,0,0,0,1};
But, in order to help you out more, I need to know which sprite routine (if any) you are using. The latest one in bwang's (somewhat old) static library would take a different format.
Also, the color parameter is an integer from 0-15, with 0 and 1 representing black and 15 representing white.
