@mitu thanks very much for the quick reply

I should probably just tell you that i did order and received the 2x Tomee NES to USB adapter. They work flawlessly with my two original NES-004E controllers. I have been using them for the past 2 weeks playing top NES games. :-) I am still waiting for the PSX to USB adapter to arrive. At the moment i have no way of testing my PSX Analog controller.

@tjayhawk32 I don't think the order matters. The Pi has only 1 internal USB hub, any port would go over the same data path.

@mat Element 14 is one of the main distributors for raspberry pi, it is probably as official as it gets.

Please include the information requested https://retropie.org.uk/forum/topic/3/read-this-first in when opening a support topic. Have you read the documentation for enabling a 6 button controller in RetroArch ?

Final Update: Turns out it was my charger all along . Here is what I ended up doing. From my Pi3 I run a DC Barrel Jack to Micro-USB B Male Connector (http://a.co/d/4yVdU3c) . Then from the barrel jack I have a normal power supply (http://a.co/d/7j0vMr3) . No voltage issues at all and everything seems fine.

@cyperghost Alas, I don't now how ES and its emulators will react to this on runtime. I didn't use it myself (yet), but researched it only because of this thread and a general interest for future use. As for specific drivers, I don't have any experience in that either, but as long as they depend on the devices in /dev/input/, they should react to disabled devices there accordingly, I suppose.

@edmaul69 Great :-( Thanks for the warning

@chrisbati Unfortunately, c64 and spectrum joysticks only had one fire button command, no matter how many physical buttons there were. The adapter may support more buttons on the output, but if it has no difference in the incoming signal, it won't be able to do anything else.

For default controller mapping here is a link: https://github.com/RetroPie/RetroPie-Setup/wiki/RetroArch-Configuration#default-joypad-hotkeys Oops mitu just beat me to it

@xd3l Turns out that I can't use any of my USB hubs with this. If I do, the Tomee Adapter doesn't pick up, though everything else does. If I take the hub out of the equation then the NES adapter works every time without issue. This is unfortunate because I was hoping to rig up a player 2 port, thus needing a USB hub.

Ah... Thanks DD_Indeed. I'll give it a shot tomorrow and see how it goes.

@richiep I have the deadzone issue as well. I'm using the Ram controls USB adapter, and I think the deadzone is programmed in the controller. When I run a jstest on it, I can see the deadzone in the numbers, so I haven't gotten into the mame settings. I use advmame, so I'm not sure about the parameters in Mame4all, but there must be some. Can you try advmame? What is the USB adapter you're using? I was going to try to configure a Teensy. ws

@ortsac Damn, I don't want to strip the wires to my SNES controllers or take apart my console to make a panel. I'll be using an HD CRT TV. It'd be if a more straightforward adapter was invented. But oh well. Thanks for the help.

@Caligula88 first thing to note: Please do not post a support request without first reading and following the advice in https://retropie.org.uk/forum/topic/3/read-this-first Now, 2 questions: Did you configure your joysticks on emulationstation? Paste here the output of this command: ls /opt/retropie/configs/all/retroarch-joypads/

Update: Fixed the input lag issue I was experiencing. Issue: Having two PS4 USB wireless adaptors plugged into the retropie at the same time was causing interference in the Bluetooth signals causing variable input lag when playing multiplayer games like street fighter iii: third strike. Fix: I got a USB extension cable, plugged one end into the retropie and connected one of the dongles into the other end. This allowed me to create a bit of separation between the two USB adapters which was enough to remove the interference they were running on each other. Hope that helps anyone else running into this issue while using multiple PS4 controllers connected to multiple USB dongles on the retropie. Btw, the dongles have worked out really well in my experience, much better (in terms of input responsiveness) than connecting the PS4 controllers directly to the Bluetooth from retropie.
