"I was fed up with not being able to reassign functions to individual Raildriver buttons. So I built myself a buttonbox, which I would like to present here. I used standard arcade joystick PCB, because I wanted to make it as cheap and simple as possible.
The biggest issue for me was the long delay when using the Raildriver alerter button and the inconsistent positioning of the PZB buttons. Additionally, I wanted a more intuitive placement of the door opening buttons. With this device, the game is now much more immersive. I use JoyToKey software to assign individual buttons to specific keyboard shortcuts.
So now I have big/easy to localize SIFA button. Two big levers for PZB acknowledge and PZB Free, a CMD 40 button. Additionally key for cab activation, emergency brake and two green buttons for left/right doors... and more. If anyone would like to build themselves something similar I'll happily give more precise instructions."
