# Sources of Title Screen 2026.10.09

Every fact in the archive is a row of `assertion` (evidence.jsonl) naming its source. The archive copies facts and identifiers only: no description, review, score, artwork or page text from any source. Dropping a source is a configuration line and a rebuild; this page shows what each one contributed.

Build inputs: libretro-database `fbeefcb4`, MAME 0.289 (mame0289), MAME software lists `5218b91`, web sources fetched 2026-10-09 (Wikipedia pages pinned to the revision ids in their locators). Redump DATs: .
