riting to one register
resets both joypads. Once the writing is done, each read from each register
will return the state of one button, in the following order:

<P><TT>Read # Button&nbsp; Read # Button</TT>
<BR><TT>&nbsp; 1&nbsp;&nbsp;&nbsp; B&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
9&nbsp;&nbsp;&nbsp; A</TT>
<BR><TT>&nbsp; 2&nbsp;&nbsp;&nbsp; Y&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
10&nbsp;&nbsp; X</TT>
<BR><TT>&nbsp; 3&nbsp;&nbsp;&nbsp; Select&nbsp;&nbsp;&nbsp; 11&nbsp;&nbsp;
