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

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.

Used these inside my X-Arcade sticks to replace the keyboard encoder that does not work well in RetroPie... Encoder works great and right out of the box. Have 2 of them installed and both show up as separate controllers. Havent noticed any delay playing stuff so far! Install is super easy as each switch (buttons and joystick) connection has a sense and ground, so no daisy chaining grounds from one or two points. Only beef is the cables are quite short so you cant have the controller too far from the buttons. I could make it work but some of the wires are pretty tight. Keep that in mind if you cant install encoder right next to buttons and sticks.

There seems to be TWO versions of this board... this version has the all important RED +5v out connector for light up buttons!

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.

Works great
