@subs Awesome, thank you! That's what it was. My Tankstick wasn't shipped with a serial to USB adapter. I was buying them from my local store. I just got a hold of the X-Arcade converter and it works perfectly. Your answer helped me uncover a solution. Thank you!

@subs Thanks for the help. On one end of the tankstick I have a USB output and a green mouse serial output, and the other end of the stick I have a DB9 and purple keyboard serial output. I've tried every combination of plugging these in. I've attached a USB to serial on the keyboard output going into the Recalbox. What am I doing wrong? How do you have your Tankstick hardware going into the Recalbox?

@Nachtgarm Thanks for the response. I have read both of those links. Everything from a software perspective is complete, and the red light is active on the stick, but the stick isn't recognized by the Recalbox. So I'm not sure if it's something with my hardware configuration- that's my question.

Hey guys, long-time viewer, first-time poster. I swear I've searched the web high and low for my question and can't find the answer.

I have a I have an X-Arcade Tankstick and have a serial to USB converter going to my Pi3 w/ Recalbox Version 4.0 beta 5. The stick lights up, but the system doesn't recognize anything. I'm not sure if it's a hardware problem or a software problem. I've read some places that you must have a PS/2 plugged into your system and some others that they are using an adapter.

Is anyone able to tell me what the correct hardware configuration into the Pi is? Thank you!
