CrankBoy Manager is a free, open-source desktop application for transferring Game Boy and Game Boy Color games to CrankBoy devices. It communicates with connected hardware through a USB serial connection. Users can add individual ROM files or drag entire folders into the application for processing. ZIP archives are automatically inspected and supported ROM files are extracted. Game Boy files can be compressed into GBZ format to accelerate transfers. The application identifies supported games through CRC32 checksums and automatically downloads matching cover artwork. Batch transfer queues process multiple files sequentially while displaying individual and overall progress. An optional automatic restart refreshes the CrankBoy library after transfers. Built with Python and PyQt6, it supports Windows, macOS, and Linux.
