Rebuilding an archive
Arcade emulators read their BIOS files from a ZIP archive.
The collection keeps a recipe for each archive. It lists the files inside, in order, with their fingerprints. The recipe and those files make the archive again. No copy from elsewhere is needed.
Rebuild one archive
In a copy of the project:
python scripts/romset_recipes.py --build neogeo.zip --output-dir rebuilt
Each archive of that name is made under rebuilt/, in the folders it has in
the collection. It is checked against its recipe before it is kept.
Exact or canonical
- Exact: the same bytes as the archive in the collection. 1,796 of 2,231 archives.
- Canonical: the same files inside, packed another way. 435 of 2,231 archives.
An emulator reads the files inside, so both work the same. A setup that checks the whole archive by its fingerprint needs the exact one.
Every option of the command: tools.
