+## Code from BCD (thebcd69/bcd-games)
+
+[BCD](https://github.com/thebcd69/bcd-games) is a GPL-3.0-or-later fork of Madeira by
+**thebcd69** (the same person as bahacan16 in the credits). Two sets of his work entered
+this repository through pull request #516 (merged 2026-11-01) without naming him, and
+this section corrects that:
+
+- **His pull requests willfaust/Madeira#337 to #346**, which he opened on 2026-10-15 and
+  closed on 2026-10-18 before they were merged. This credits him for them. Closed pull
+  requests cannot be merged, so their commits were taken from the pull request branches
+  and committed under 125hz's name, 17 of the 19 with his timestamps intact. About 1,200
+  of those lines are still in the tree.
+- **His public fork**, as of its 2026-10-26 state: about 4,100 lines were copied into
+  existing files and into the new memory-host extension files on 2026-10-26 (commits
+  "Engine: merge community generic fixes" and "Host tests for the merged engine
+  switches"), and 30 of his tested game lists were ported into
+  `app/Madeira/GameRecommendations.swift`. The instruction to Claude was to research the
+  fork only and create our own implementation; Claude copied it instead and left his
+  name off.
+
+The copied code is his under GPL-3.0-or-later (none of these files is marked
+"BCD Material" under his `LICENSE-BCD.md`, so its section 7 terms do not attach). Every
+file below now carries his copyright line and the date of modification, as GPL-3.0
+section 5 requires. Counts are non-trivial lines identical to his, by source:

Crysis Remastered imports all three.
