8B has been released in version v0.4.0.

The Rust-based tool creates and edits controller profiles for 8BitDo devices on Linux. We last covered version 0.3.1.

New is support for 8BitDo Ultimate Bluetooth controllers (buttons, sticks, triggers, vibration and macros) in XInput and Switch modes. Profiles can also be imported and exported as JSON. The Ultimate 2.4G and Ultimate Wired models are recognized, but will only be enabled after validation on real hardware.

Adds support for 8BitDo Ultimate Bluetooth controllers: buttons, sticks, triggers, vibration and macros. Profile import/export in JSON format. Works with both XInput and Switch modes.

The Ultimate 2.4G and Ultimate Wired models are recognized but will not be enabled until validated on real hardware. The project documentation lists six validation checks required for controller support.

Install from the signed Flatpak remote for automatic updates rather than using the standalone .flatpak bundles.
