Proposal for gamepad_drv standard?

I've uploaded a simple keyboard version of gamepad_drv_001 to obex. Any game that requires NES
controls and uses gamepad_drv_001 should work find with this driver.

I'm getting ready to do a version for the Nintendo 64 and PropJoy as well..

Got a proposal for the game developers here:
If we could get everyone to agree to use this type of format for their creations, then
adapting any device could be as simple as changing the file before compile.

Consideration?

    In Spintris I have a controller setup that uses the keyboard, Hydra joypad and Hybrid joypad setup in one gamepad file. It made it easy because from game engine's perspective, it saw it as one controller (there wasn't different setups for the different inputs).

    Excellent, standards are the way of the Dark Side, I love it [noparse]:)[/noparse] Seriously though, without DirectX we would be in the stoneage of gamedev still, so the more standards for the hydra the better, so people can concentrate on making games and not re-writing basic drivers.

    N64 gamepad_drv_001 submitted to obex, waiting for approval.

    PropJoy/Hydra controls next. (easy stuff)

    With the expanded focus of this forum, this is a thread that deserves a revisit.

    My original N64 conversion can be found here:
    obex.parallax.com/objects/250/

    I'm going to switch LOADRUNNER and SPYDRIVER to use a separated "gamepad_drv_001.spin"
    and so some testing with some of the other Propeller configurations in my collection starting with the Hybrid.

    OBC,

    I just finished soldering my PropJoy adapter and I'm looking for someway to test it. Did you ever finish the PropJoy driver for Atari joysticks? Does the PropJoy work with the Hydra NEC driver? Comments welcome.

    By the way I just viewed your Propeller Arcade Atari Interface Test - great job. Boulderdash is one of my favorite games.

    @Forrest

    No, but I think I can help you with it.

    Can you give me an idea of your connection points (I/O) to the Atari switches?

    Thanks!

    The PropJoy documentation is here ucontroller.com/documentation/propjoyDoc.html

    Each joystick port is connected thru a 4021N, and the pin outs to the Propeller are exactly the same as uController's NEC adapter ie. P3-Clock, P4-Latch, P5-Player1 Data and P6-Player2 Data.

    The only other reference I found to PropJoy on these forums is this thread about Defender - which apparently works with the PropJoy http://forums.parallax.com/showthread.php?p=697458

    IIRC, the PropJoy should work with any NES compatible program (which uses a single fire button)
    simply by changing the bit mask a little.

    Here's some NES code from one of my programs..

      ' NES bit encodings for NES gamepad 0
  NES0_RIGHT    = %00000000_00000001
  NES0_LEFT     = %00000000_00000010
  NES0_DOWN     = %00000000_00000100
  NES0_UP       = %00000000_00001000
  NES0_START    = %00000000_00010000
  NES0_SELECT   = %00000000_00100000
  NES0_B        = %00000000_01000000
  NES0_A        = %00000000_10000000  
  
  '' joypad serial shifter settings
  JOY_CLK = 3
  JOY_LCH = 4
  JOY_DATAOUT0 = 5
  JOY_DATAOUT1 = 6



    Adjusted for the PropJoy.

      ' NES bit encodings for NES gamepad 0
  NES0_RIGHT    = %00000000_00001000
  NES0_LEFT     = %00000000_00000100
  NES0_DOWN     = %00000000_00000010
  NES0_UP       = %00000000_00000001
  NES0_START    = %00000000_00010000
  NES0_SELECT   = %00000000_00100000
  NES0_B        = %00000000_01000000
  NES0_A        = %00000000_00100000
  
  '' joypad serial shifter settings
  JOY_CLK = 3
  JOY_LCH = 4
  JOY_DATAOUT0 = 5
  JOY_DATAOUT1 = 6



    You might need to ditch the 00000000_'s but it should work. In this example I've setup NES0_A to the fire button.
