EG STARTS Arcade 2 Player Zero Delay USB Encoder to PC Games Controller Arcade Joystick Buttons for PC, MAME, Raspberry Pi, Arcade1Up - 3X Red Power Outputs (5Pin + Sanwa Style)

Works good. And arrives quickly. Just what I needed

The board was fine and worked like it should. It did not come with enough connectors for the board. They offer products to make it while at a reasonable price. 9/10

When you need to use custom buttons (maybe for a color EG doesn't have in their kits), this is the way to go. Comes with the board and all of the wiring you need, and it's very easy to set up and even incorporate LED buttons if you want. Works like a champ, very responsive, no complaints.

Great quality, fast delivery. Quick returns with no hassle for items that didnt need for my Arcade

Just plug it in and the joysticks are working.

Perfect for my USB custom box I made for my 3D printed joystick for American Truck Simulator!

I used a KVM to switch between a MiSTer and RetroPie. The encoders would loose connection when switching to RetroPie. MiSTer was pretty solid. Without KVM works fine on RetroPie.

These don’t have the crystal oscillators, but I had no issues installing both to the same machine for two player games. Just make sure you connect the wires the same on both boards. Must be connected identically.
