libretro-finder 0.1.0

Command line utility that looks for specific BIOS files for libretro cores and, if found, refactors them to the expected format as documented [here](https://github.com/libretro/libretro-database/blob/4a98ea9726b3954a4e5a940d255bd14c307ddfba/dat/System.dat).

libretro_finder

Simple command line utility that looks for specific BIOS files for RetroArch cores and, if found, refactors them to the expected format as documented by Libretro here. This is useful if you source your BIOS files from many different places and have them saved them under different names (often with duplicates). This script is able to find these exact BIOS files by comparing their hashes against their known counterparts.

This repository does NOT include the BIOS files themselves.

Only requires Python 3.6 (due to f-strings, type hinting, enum, etc.) and should work on Windows, Linux and Mac.

Example of usage:

You can safely use the system directory of retroarch as output_dir since we also check existing files against the known hashes (we'll only dump them if they're not present yet). Any folder structure expected by libretro is respected (if documented).
