What adaptor must have for my computer? the joystik have not usb.

Hi,
I too have this exact same joystick so when I tried to plug it into my new pc (that I built 2 yrs ago as of Feb.14,11) I had to use a: 15-pin to USB adapter with chord.
I got it from eBay.ca in the $5-$10 range shipped to me from Chnia.

It's called the: Super Joy Box 7 USB Gameport Adatper

They are still available from eBay.ca & eBay.com as of Dec.06,10 (the time of writing this posting).

For me it wokrs, but only 1/2 - as in:
- the fire button + 3 other buttons - work fine
- the HAT switch (4-way) - refuses to work
- the full range of the joysticks motions are reduced (on the right side)

Because of these limitations I had to learn to used the keyboard buttons to fly planes & choppers in the pc game - GTA:SA.
I plan to buy the pc game GTA4 as soon as it goes down in price of it's current $20 & buy a...
Saitek Cuborg Graphite Joystick PS21 that is newer and uses a USB connection.
