Easyget 2 Player Zero Delay Generic Game Controller USB to Joystick for MAME & Raspberry Pi 1/2/3 RetroPie DIY Projects

Works great with RPI 3, though the red LED on the board is always lit. I assumed the green LED would be lit if the board is functioning properly.

good price and fast shipping.

I bought these to update an existing MAME control panel setup. Unfortunately, the delay between the control action and the on screen reaction is so long that it makes games unplayable. Very disappointed.

Worked great on my RetroPie setup! Easy to wire with provided harnesses. Plug and Play from a usb standpoint.

works perfectly

I already had one of these zero-delay encoders that came with a button kit I purchased, so I knew what I was getting. These work perfectly and are super easy to wire up.

Works

Works fine.

I was modding an arcade1up cocktail table with a Windows 10 Big Box setup. I thought K1-K10 could be in any order but I was definitely wrong. When using Retroarch with the Mame (2016) core as the emulator, Midway games like NFL Blitz and NBA Hangtime were showing in the button diagnostics, that a few button combinations were not registering. For example, I couldnt do button combos with Turbo in those games, meaning I couldnt shove in NBA Jam, or Stiff Arm on NFL Blitz. It turns out, when you go into Mame key mapping, this board shows K1 as RY-, and K3 as RY+. It also shows K2 as RX+ and K4 as RX-. This wouldnt be a problem unless you need to hold down K1 and K3 or K2 and K4 simultaneously because these are joystick assignments... meaning it will not allow you to hold both joystick left and right at the same time. So essentially my workaround is just map Buttons 1-6, only including one RX and RY so I can press all six buttons at the same time without conflict. So my button configuration if anyone wants it is for Button 1-6 is K7,K9,K2,K3,K5,K6 which translates in Mame as A,B, RX+,RY+,L,R. My Start button = K10, and Coin button= K1. And I used L2 which is K8 as a back button for Big Box. The only problem this would give is if I need to Press Coin button with Button 4 - I cannot do this key combo simultaneously. I hope this helps.

love these for my Raspberry Pi arcade table
