CrankBoy Manager
Cross-platform desktop app for transferring Game Boy ROMs to CrankBoy
...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.
