This repository provides a BIOS management tool for RetroArch emulators. It audits local firmware directories, verifying each file against known checksums to identify missing or incorrect system files. The tool functions as a checksum-based file verifier and a collection auditor, ensuring that your emulator BIOS files are correct and properly placed for runtime.
Beyond basic verification, it automates the detection of missing BIOS files and can download verified replacements. The tool generates custom firmware packs tailored to specific platforms or emulators, resolving the correct target directory structure for each system. It also supports building ready-to-extract ZIP archives and staging a local collection for correction.
The project includes a browsable inventory of known firmware across platforms, with verification status and gap analysis. It documents the exact extraction path for each platform to guide correct BIOS installation.
