# DaemonBite PC Engine / TurboGrafx-16 Controllers To USB Adapter
## Introduction
This is a simple to build adapter for connecting PC Engine / TurboGrafx-16 controllers to USB.
NOTE: This adapter is in BETA and not yet properly tested.
This is a simple to build adapter for connecting PC Engine / TurboGrafx-16 controllers to USB with turbo functionality support.
The input lag for this adapter is minimal (should be less 1ms average connected to MiSTer).
