I am confused about how the GPWiz49 pinout maps to joypad buttons. I am in the process of trying to finish wiring up a control panel before our 4th of July party tomorrow (pressure, pressure! :o) and I'm at the point where I need to start wiring up 2 GPWiz49s. I have the solder versions that I bought used. They came already soldered up to 2 Williams 49 way sticks. I've plugged them in and verified that the joysticks work properly. Now, I am ready to wire up 4 buttons per player, a start/coin per player, and 1 pause/1 esc (14 total) -- I'll be using leaf switch buttons. I have a bunch of questions that I'd like to understand before pulling out the soldering iron. 1) Is there some default mapping from the pinout on GPWiz49 PCB to gamepad buttons that I should follow? I.e. right now, the 49 ways are soldered into 1-8, G, G, and V+ on the PCB (essentially the leftmost 12 positions on teh PCB, looking from the top). Remaining pins are: B D F H | J L N P | U D L R | G [] A C E G | I K M O | R L D U | G S Does "A" map by default to a gamepad button? If I test the joystick in windows, there are buttons 1-28. How do buttons 1-28 map to the pinout above? A=1, B=2, etc? Some other way? What are the G G and S all the way to the RHS of the pinout? 2) Is there a guideline or a standard I should follow to make my life easier when I configure mame? 3) I am using Mala, so I think I need to make sure my admin buttons are one of the first 12? 4) When I go to map gamepad buttons in mame, do I really have to do it for *every* game, or can I set up a default to be applied to all games? Thanks! |

Go to www.groovygamegear.com and check out the page for the gpwiz49. Here's a direct link to the PDF on that page telling you what connections go where: http://groovygamegear.com/PDF/GPWIZ49_MAX.pdf When you start a game in MAME and hit the tab button, there's an option for setting up controls for all games and for the individual game you started. |

Duh! :banghead: I am sorry for asking such an obvious question. In my rush, I didn't look at that document carefully enough (the dangers of skimming pdf on a computer). Thanks for the tip in mame, too. I didn't realize that control selections could be applied across all games. Thanks and again, sorry for the obvious question(s). :-[ |

But now I have a new question... In the PDF, there are two sets of UDLR labels. Looking at the PCB with the pinout on the bottom: Does UDLR RLDU map to 1357 2468 or map to 8642 7531 ? Thanks |

The upper set is "1" and the lower set is "2". The 40 pin header should show a P1 and P2 to the right. They coincide with the above. But here's a PDF that should make it easier for your board version. RandyT |
