X1 Box is an Xbox emulator available on Android for .99 through the Google Play Store. It is a fork of the open-source Xemu emulator, with its source code publicly available on GitHub. The decision to monetize X1 Box without compensating the original developers has raised ethical concerns. The Xemu team is developing their own dedicated Android version. Performance evaluations indicate that X1 Box has inconsistent performance, often capped at 30 frames per second, which affects gameplay.
