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.

@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.

@peg Many thanks for all this work too. Just to let you know I had to tweak this guide slightly as when running 'make modules_prepare' I got errors on Retropie 4.8 running on a pi zero 2W. It seems that I had to install 'libssl-dev' first before this command. Can confirm that after this all other steps worked, rebooted and rumble working on both pads as expected on the Trixes adaptor.

For those getting the same errors, here's a full update to @peg guide (I take no credit and thank @peg for this easy tutorial and just helping anyone with the same issue)

@Graboid

Thanks anyways :) I have opened a new post.

@sfc_k i can comfirm that all of raphnets adapters work. I have used all of his usb boards and adapters and his wii adapters too.

@hansolo77 said in Problem with Genesis/MegaDrive USB adapters (RetroUSB and Mayflash brand):

Would you be against buying a 3rd party controller?

I'm a stickler for the originals I must say. I've had bad luck with pretty much every single after market controller I've ever tried going back even to the 80's. Even had bad luck with 2x 8BitDo's everybody seems to love. Only lately, ~20 years later, am I having problems with the real console controller brands for the first time (and even that's not their fault as they're now antiques, and I'm using them on a computer and not a console).

@edmaul69 said in Problem with Genesis/MegaDrive USB adapters (RetroUSB and Mayflash brand):

the biggest issue is the cables are crap.

I'll deal with re-wiring them if I have to, in like another 20-30 years when the controllers are going for $100+ each because they're so rare ;)

Right now I have working properly: 4x+ NES controllers, 2x SNES, 3x Genesis, 2x PS1, 2x PS2, and a bunch of Xbox 360 wireless controllers....so even though it took me a ton of trial and error I have at least a set for each proper console I emulate so I'm just leaving it at that. It was just a shame that it took so much trial and error to get to this point. I want to have a 2-player set of controllers for each console, and a backup or two so I'll probably pickup another SNES and Genesis controller, but that's about it.
