Are you trying to do teh signal conversion in hardware?
If you are, you can just use a standard gamepad driver.
The gravis gamepad driver seems to work better though.
I believe it is because the gravis driver uses a dead-zone.
A dead-zone allows some movementn to the analog signal,
without registering movement. All devices normally use this
but it really makes sense for a gamepad because a direction
is either pressed or not. no slightly pressed.

If you are going to just "cross wires" and do everything in
software, you have several options. First, there are
several progs already out there if you dont have
to do it yourself. I belive they all use the parellel
port though. Most do not use standard gamepad driver.
they work by a keyfake routine. This is where the
prog makes the computer think a button on the keyboard
was pressed. If you want to do it yourself and you
want to use the gameport, download the win(what you run)ddk
from microsoft's site. It is large but should get you
started. To make a advanced driver, you may need
to buy a book. THere are profesionals who just
make gamedrivers!!!
hope it helps,
sandytf
