23 Introduction
24 ============
25
26 The joystick parport drivers are used for joys
27 originally designed for PCs and other computer
28 that, PCs usually lack the right ports to conn
29 port, because of its ability to change single
30 both output and input bits is the most suitabl
31 connecting such devices.

33 Devices supported
34 =================

36 Many console and 8-bit computer gamepads and j
37 following subsections discuss usage of each.

39 NES and SNES
40 ------------

42 The Nintendo Entertainment System and Super Ni
43 gamepads are widely available, and easy to get
44 connect to a PC, and don't need much processin

46 with them.

48 All NES and SNES use the same synchronous seri

52 input lines is assigned to each gamepad.
53
54 This protocol is handled by the gamecon.c driv
55 you'll use for NES, SNES gamepads and SNES mic
56
57 The main problem with PC parallel ports is tha
58 source on any of their pins. So, if you want a
59 for your pads, use either keyboard or joystick
60 cable. You can also pull the power directly fr
61 wire is +5V).
62
63 If you want to use the parallel port only, you
64 some data pin. For most gamepad and parport im
65 needed, and I'd recommend pin 9 for that, the
66 hand, if you are not planning to use anything
67 port, anything between and including pin 4 and
68

70
71 Unfortunately, there are pads that need a lot
72 ports that can't give much current through the
73 case, you'll need to use diodes (as a preventi
74 port), and combine the currents of two or more

92 NES and SNES pads have two input bits, Clock a
93 serial transfer. These are connected to pins 2
94 respectively::
95
96 (pin 2) -----> Clock
97 (pin 3) -----> Latch
98
99 And the last thing is the NES / SNES data wire
100 each pad needs its own data pin. The parallel

107
108 Note that pin 14 is not used, since it is not
109 port.
110
111 This is everything you need on the PC's side o
112 the gamepads side. The NES and SNES have diffe

151 In the era of 8-bit machines, there was someth
152 for joystick ports. They were all digital, and
153 connectors (db9). Because of that, a single jo
154 hassle on Atari (130, 800XE, 800XL, 2600, 7200

233 Multisystem joysticks using db9.c
234 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
235
236 For the Multisystem joysticks, and their deriv
237 was written. It allows only one joystick / gam

247 (pin 3) -----> Down
248 (pin 4) -----> Left
249 (pin 5) -----> Right
250 (pin 6) -----> Button 1

252 However, if the joystick is switch based (eg.
253 you might or might not, depending on your para

261 gamepads the pullups are not needed.
262
263 For joysticks with two buttons you connect the
264 the parallel port::
265
266 (pin 7) -----> Button 2
267
268 And that's it.
269
270 On a side note, if you have already built a di
271 the digital joystick driver 0.8.0.2, this is a
272 driver, as device type 8. (See section 3.2)
273
274 Multisystem joysticks using gamecon.c
275 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
276
277 For some people just one joystick per parallel
278 want to use them on one parallel port together
279 possible using the gamecon.c. It supports up t
280 including 1 and 2 buttons Multisystem joystick
281
282 However, there is nothing for free. To allow m
283 once, you need the sticks to be purely switch
284 not to need power. Just a plain simple six swi
285 joystick can do more (eg. turbofire) you'll ne
286 if you want to use gamecon.c.
287
288 Also, the connection is a bit more complex. Yo
289 and one pullup resistor. First, you connect th
290 the same as for db9, however with the diodes b

317 The TurboGraFX interface, designed by

320
321 allows up to 7 Multisystem joysticks connected
322 Steffen's version, there is support for up to
