Migrating from EmuDeck
Kyaraben can scan your existing EmuDeck directories and show you what you need to copy over: ROMs, BIOS files, saves, and EmulationStation DE metadata. Files are not moved automatically; the tool shows you what exists and where Kyaraben expects it.
In the app, go to Settings > Import. From the CLI, run kyaraben import scan ~/Emulation. See CLI reference for output options.
