Update: the developer behind X1 Box (the $8 Xemu port on the Play Store) has now released their app for free on GitHub. I'm glad that they are offering a free version themselves, and hopefully the Xemu team will make the official port they mentioned last week. https://github.com/izzy2lost/xemu/releases

Here is my video on the app, the performance is not there yet, but I'll be keeping an eye on this: https://youtu.be/3FLlaGUzm2Q
