RSDuck has released a new version of the Gameboy Advance Emulator for the Nintendo Switch:

This is probably going to be the final version of VBA-next. But don't worry, we're working on bringing another offspring of VBA, VBA-M, with a lot of feature than retroarch's VBA-next to the Switch.

Changelog:

Cheat support. They can be directly entered from the emulator, just enter the cheats menu from the pause menu.
Fullscreen UI in docked mode(though the implementation isn't optimal, also currently not tested)
Some minor improvements and adjustments, seriously
