@stoney66 said in Two Player games: Different / same joystick(s) possible?: @top-specci Sorry thought you were using a different controller that you have to wire each button to a usb encoder, what you have doesn't need anything special other than plugging it in. As written repetitive before, it works, but if I select for P2 to use the same joystick as P1 (the big one ("Dragonrise") from a one player bartop), this is than for all games. So in this configuration it's not possible to use a connected USB joystick for P2 (i.e. for sporting game where two players play at same time). I can not change this for this game (because inside the Game Mame emulator I don't see the USB Gamepad)

@mitu Thanks, save/load is working. But strange, usb calbe keyboard is connected, also arrow-keys are working inside the retroPie, but in the Game-Menu no key is working, also no (i.e.) "5" to start the game. I must use the virtual keyboard (select key). But OK ....

Ok so this is solved. The good news is at least as far as I can tell the Sanwas don’t go bad after only a year of use. This was a wiring issue with some of the connections I made between the five wire harness and the wires to the usb encoder coming loose, ironically and randomly several at a time. I don’t always supervise the kids’ use of the arcade so it is also possible this wasn’t REALLY random, maybe one of the kids was particularly rough or lifted up the control panel lid and pulled some of the wires. All fixed up now! Now I have a few extra Sanwas for spare parts though! (Only figured out it was a wiring issue once I installed the new joysticks and problem was still occurring...)

@arduinoGamepad Emulationstation is using SDL's joystick sub-system to handle joysticks, my guess it's not detected as such. There's a similar sdl-jstest utility -which is similar to jstest - that tests whether the joystick is detected by SDL. To get it detected by ES, try one of these - in order add a local udev rule to force the device to appear as a joystick: SUBSYSTEM=="input", ATTRS{idVendor}=="<VID>", ATTRS{idProduct}=="<PID>" ENV{ID_INPUT_JOYSTICK}="1" substituting VID and PID with the values you get for your controller from running lsusb. Use Xboxdrv to make your device be seen as an Xbox driver.

@Baxter I didn't upload it. Check out more restoration videos from TnT Amusements on the official channel here

@mediamogul said in Another Daphne joystick question...: Once it's better integrated into RetroArch, perhaps it'll be a non-issue. Oh yes, I'm hoping soo eagerly for this.

You are correct about the 49-way control, and yes it can be replicated. I'm currently using MAME-2003 and a PS4 controller. The left analog stick absolutely works well with Sinistar. When playing, gradually rotate the stick and you will see it handles more than 8-way control. FWIW: I couldn't get the same results with MAME-2003-Plus. I think it has special configurations to handle analog, but I never researched, as 2003 (standard) does the job well.

this might need a quirk fix. Can you post pictures clear ones of player one and two wiring for buttons and joystick

@Foxsec said in Joystick Conflicts: I was writing down every step and making a code box for everything that came up and I tried that rmmod that Mitu suggested and i checked the quirks file after and it worked! Both set of joysticks and buttons are now configured Thanks so much for your help guys, really really appreciate it :) thats wierd, for me it would not work with modprobe and i remember reading somewhere that it was supposedly blocked, but whatever. atleast it works for you now.

Simple comment. I had the same issue but my lowerBound had to be fix to value 490. It's important to check the value when your stick go back in place. My left stick showed a value of 491 when It came back from left to center. Now, Everything's working fine I suggest to use joy.cpl to find It. https://www.pjrc.com/teensy/td_joystick.html

This guy here had the same problem and he found a way of making it work. Apparently the way to go is to configure retroarch to use a standard keyboard then swapping the real keyboard to the ipac.

Thanks for your help and advice. I got it working on a config that isn't perfect in the menu, but works great in game. With the other system emulators working fine my only concern right now is the speed of the N64 games, and whether or not I want to attempt to overclock my Pi 3 B+.

Woo Hoo! The controls are now working for Archon and all the other c64 two player games. Dudleydes you're the man - Thank You!

@TheBlueBanner said in USB HUB not detecting Joysticks: https://thepihut.com/products/4-port-usb-hub-usb-2-0. So, I received this USB hub. It worked! The only issue I have is that there doesn't seem to be enough power going to the LED lights, and they are dimmer than what I would like. I am not sure if there is anything I can do, but it worked none the less.

I just added an exec functionality to my multiplexer: The idea is, to allow external programs to be executed on a button press. This can be used to enable/disable special functions which are triggered by external executables: Here is a demo and you get an idea why I need this functionality:

@naughtjosh How did you connect the controller to the GPIOs ? Did you install any of the additional drivers needed for such setup - https://retropie.org.uk/docs/GPIO-Modules - ? Simply connecting a few wires to the GPIO pins is not enough. Ideas that don't require any downloads? Set-up your PI on a location where you have internet, just in case you'll need a driver to be downloaded or use your phone as a WiFi access point.

@mitu I got it working after thinkig about it i thought the easiest solution would be to delete the software and put a new copy of retropie on it.
