- Introduction:
-
- Some PC games are much better playable with gamepads than with normal
- (analogue) joysticks. These gamepads work just like the digital joysticks
- we know from Amiga/Atari ST/C64. But they got a circuit that converts the
- digital signal into an analogue one so that the PC can handle them as
- analogue joysticks. To use these gamepads with your Amiga you have two
- choises:
- 1. Open the gamepad and make some changes in it
- 2. Build an adapter so that you can use any PC gamepad without making changes
-
-
-
- Parts You Need:
-
- 1x DB15 female connector
- 1x DB9 female connector
- 2x 22K resistor
- 2x 8.2K resistor
- 2x 100K resistor
- 2x 120K resistor
- 2x 33K resistor
- 6x BC549C (transistor) or equivalent (like BC237C, BC238C, BC239C, BC547C,
- BC548C)
-
- and optional (see below): 2x 82K resistor and 2x 100K potentiometer
-
-
- You can set up the whole adaptor on one of these experimental-boards, so
- you don't have to solder anything (maybe except the wires to the connectors)
- and make sure it works. Afterwards you can solder the parts on a breadboard
- and put it in a suitable box.
-

-
- Compatibility:
-
- I have tested the adapter on two Amigas and on C64 with these gamepads:
- QTRONIX Orion 95, QuickShot Starfighter 5 (QS-191) and Gravis PC GamePad.
- It also works fine with my analogue PC joystick (QuickShot Warrior 5).
- Most analogue PC joysticks have trimmers for calibration that allow you to
- adjust them to the adapter.
- It should also work with digital PC joysticks like COMPETITION PRO, but
- I haven't tested that.
-
- Nevertheless you could have a gamepad/joystick that produces other voltages
- than the above mentioned gamepads, that means you need to change at least
- two resistors. Therefore I included a more flexible version of the adapter,
- that lets you calibrate the circuit to work with your gamepad/joystick.
- You just have to replace the two 120K resistors with two 82K resistors and
- two variable resistors of 100K (see "Adjustable_Adapter.iff").
-
- Note:
- If you have the adapter connected to your computer without a gamepad/joystick
- plugged in has the same effect as if you press a connected stick/pad back and
- right. This is no bug, because if you move the pad or stick to the right,
- there will be a voltage of 0V at pin 3 (PotY). Analogous with pin 6 (PotX).
