-ChuniIO driver for [Brokenithm-Android](https://github.com/tindy2013/Brokenithm-Android)
+ChuniIO/AimeIO driver for [Brokenithm-Android](https://github.com/tindy2013/Brokenithm-Android) and
+[Brokenithm-iOS](https://github.com/esterTion/Brokenithm-iOS)
 without needing an external server.
 
-It is recommended to use this with [Dniel97's segatools](https://gitea.tendokyu.moe/Dniel97/segatools/releases),
-since it allows loading 32-bit chuniio DLLs without any messy hacks.
