## chuniio-tasoller *with air tower LEDs*

chuniio driver for tasoller custom 2.0 firmware
now with working air tower LEDs when using [Dniel97 segatools](https://gitea.tendokyu.moe/Dniel97/segatools/src/branch/chuniio)  
this currently only works with the chuniio branch of segatools, but may work on the main branch in the future

thanks to:
- [**akiroz**](https://dev.s-ul.net/akiroz/chuniio-tasoller) 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
