@joestrong as the man above me stated. And when it blinks it shows 1-4 lights at once. The less lights you see the less battery power you have. You can see this when you turn on your controller on as well

This is exactly what I did. I used wire that was probably to thick so it seemed like an easier way to do it.

@SutterKane

At the moment, the keyboard is totally ignored

Did you configure it? Where is it plugged in? Do you have enough power? What is the rating of your power supply?

Is there an additional setup to be done to get the Buffalo SNES controllers
working correctly ?

Playing games via MAME

Which one? Have you set the controls using TAB? Is it a libretro emulator?

Start with this to save time....

And there are the 2600-daptor and 2600-daptor 2. There's a thread with a link to modded RetroPie for a project to support it here, so possibly that work could be integrated into the main RetroPie for the RPi A/B/B+.

@TheCatMan2000

You might look into this as a possibility.

Oh man...

I'd love an answer to this. I have two Wii U Pros and things just don't work right when I attempt use them both.

They are both registered devices via the onboard BT. As you said, they both show as being player 1 on each controller.

The wife and I get lots of crashing, random button presses, and even phantom rumbles from the unused controller when it is just sitting there. My solution has been to just disconnect one and not use it. But, that sucks.

I'd love to be able to use two Wii U Pros at the same time....

Thanks.

Thank you!

Not stupid ! I removed all clntrolers drivers, then reboot. And it now Works as expected !
Thanks

@foreverclumsy I'm also trying to get my iBuffalo controller working with advmame - did you ever get a working .rc file?

@Jofo well, being that I now have several versions of the PSX bus reader, I can talk about my results with all versions.

The original version of the driver, even with the Select button filtered, definitely had sporadic issues with input glitches. My updated version was nearly perfect after filtering the Select button. I'm pretty sure the Acknowledgement line implementation is what did it. I'm pretty confident in that one.

However, the Arduino reader is 100% perfect. So far I've needed no filtering, it all just works. I need to work on the CPU usage of the driver though, still, but for what it's worth, it should work on the Pi. Just plug the Arduino in with USB.

@MrWilliam932 you can set different controllers to different emulators. Check the link on my signature.

Mame actually is a little tricky: needs exclusive config, needs the right version of the game, but after get rid of these problems, it's a great emulator.

Cool, but I'd like to stick with a retro controller @StormJH1 Quick question, are the n64 remotes prices going up? The n64 is the next step for me, (as it says in my signature) and I don't want the prices to go up too much.

Heh that's great news! Will it work with the runcommand menus as well, or just the retropie-setup menus? In either case, that's a superb improvement! :)

I'm having similar problems with Retropie. I'm using a Picade from Pimoroni that has its arcade controls mapped as keyboard buttons through their PCB, running on a Pi3. I'm trying to configure my setup with P1 using the arcade buttons, and P2 using a wired Xbox 360 controller. I have the keyboard configured properly, as well as xboxdrv installed and enabled. I'm crossposting from the below link in an effort to get some kind of assistance, so I apologize if something sounds out-of-context

I entered manual config lines into my retroarch.cfg file to correspond to player 2 (http://forums.pimoroni.com/t/multi-player-picade/1507, my cfg is almost identical to the one themattsearle pasted). If I do a simple restart, the P2 controller will navigate all retropie menus exactly as expected, but once I load any game the controller ceases to function (P1 functionality never seems affected, which is good) until I back out to the menu with P1, not even the ingame Retroarch menu functions. Also, every game that I start has a little popup yellow text message in the bottom left corner at the start: "Xbox controller userspace blah blah is not configured"

If I open the retropie menu and "Configure Input" for the Xbox 360 controller, Player 2 inputs in games work perfectly as expected, but it has the problem with controlling P1 and P2 simulataneously. If I delete the .cfg file named after the 360 pad in the /configs/all/retroarch-joypads (the only file in there) and restart emulationstation, I revert back to the ES menus working but ingame controls not for P2. I even tried copying the input_player2_ lines from retroarch.cfg into that xbox cfg, but nothing changed.

As a last-ditch effort I restored my Retroarch.cfg back to the original unaltered backup I made (just in case I tweaked more options that could be complicating things). That had no different effects so something just isn't working as it should. How is it possible that the P2 controls can be configured manually but the emulators just don't recognize it? I think when I get home today I'm going to do a full system update to the newest version and see if that makes a difference. I spent so many hours configuring my romlists, scraping for artwork and manually configuring things that I really don't want to start from scratch on a fresh disk image.

I feel like I can't win and it's driving me mad. There has to be something simple that I'm missing and I can't figure out what. I'm fairly new to Retropie and just built this cabinet a few weeks ago. I was hoping to bring it to a christmas party this Saturday to show off to everybody, but I really just want 2-player support to work with a minimum of fuss.

@Kristopherson05 Why are you starting this thread? You already asked it here:
https://retropie.org.uk/forum/topic/5544/hotkeys-issues and @meleu answered back then on how to do it. Now two weeks later you ask this again without providing the required information. It's astonishing that you could ask "Hot keys don't work - why?" when we all know they do work. The astonishing bit is assuming that we can mind read!?
So,

but after messing whith retro arch it stopped

What does this "messing" look like?
