 chuniio driver for tasoller custom 2.0 firmware
+now with working air tower LEDs when using [Dniel97 segatools](https://gitea.tendokyu.moe/Dniel97/segatools)
+
+thanks to:
+**akiroz** for the original code and USB Protocol information
+[**Dniel97**](https://gitea.tendokyu.moe/Dniel97) for rewritting my failed attempts at making this work
+
+the current implementation may not be fully arcade accurate, but should be visually acceptable during gameplay
+this should hopefully be addressed in the future
