Not really aware of keyboard encoders at all.
At the time I started, I simply had the Sidewinder that worked awfully for my fighting games for PC. Virtua Fighter 2, Samurai Showown 2, Fatal Fury 3, SFAlpha, Alpha 2.
So I set out to run wires and build an encasing to make it a joystick via USB.
I already do something similar with my Tekken 5 stick and a Radio Shack USB passthrough.
But it's not really fair because I only have the one stick to plug into my PC or my laptop.
I want an even playing field for when friends come over.
Heck, they've even helped me in the process. To which I'm really grateful.

My goal is to have that 2nd stick made by my own two hands.
I've been eyeing some Happ parts. I know how to do what I'm doing from that aspect....I think. I just need a suitable replacement for the sidewinder I killed. Which I'm having a hard time doing.
As long as I can get the PCB intact, I can do what I want and test through Window's Gamepad/joystick calibration.
Only looking to spend $10-$15 for a pad. At this point, it could have been tossed across a room or survived a flood. Just as long as the PCB is intact and everything shows up working.
Bah, I'm probably rambling by this point.
Am I making sense, or am I just going on and on about nothing?
