+# Roxas2712 — Fork Contributions
+
+Version 1.0 · Effective 25 October 2026
+
+Copyright © 2026 Roxas2712, to the extent of rights held.
+All rights reserved except as expressly granted below or already granted.
+
+## 1. Scope and ownership
+
+This notice applies only to original contributions made by Roxas2712
+(GitHub: Roxas2712) to `Roxas2712/Gen2Recomped`, including original additions
+within modified files, insofar as he owns the relevant rights. Git history,
+pull-request diffs and source provenance identify contributions; a commit
+author or a whole-file change alone does not establish ownership of every
+part of that file.
+
+It does not claim ownership of Cedric's work, Gen1Recomp / BOIS CLUB GAMES
+work, other contributors' work, third-party dependencies, or ROM-derived
+content. Their applicable licences and notices remain in force. It does not
+grant permission to distribute the complete combined fork where another
+rights holder's permission is required.
+
+## 2. General permission and reserved rights
+
+For contributions covered by this notice and not already licensed more
+broadly, you may read and study the published source and make private,
+non-commercial modifications and builds for your own use. This grants no
+general permission to redistribute, sublicense, sell, or offer those
+contributions as a hosted service. Other uses require Roxas2712's
+written permission, except for the specific permission below and rights
+available independently under applicable law.
+
+Keep the relevant copyright, licence and attribution notices. Do not
+represent Roxas2712's contributions as exclusively authored by someone
+else. Public source availability alone does not put them in the public
+domain or grant an open-source licence.
+
+## 3. Specific permission for Cedric / UNDERdecoded
+
+Roxas2712 expressly grants Cedric (Ced; GitHub: UNDERdecoded /
+UNDERdecodedHD) a non-exclusive, worldwide, perpetual, royalty-free
+permission to use, reproduce, integrate, modify and distribute the covered
+contributions that Roxas2712 submits or expressly offers through pull
+requests to `UNDERdecoded/Gen2Recomped`, for Cedric's Gen2Recomped /
+RetroRecompiled project. This includes its renamed continuation maintained
+by Cedric, its official builds, and its commercial operation.
+
+Cedric may license the incorporated contributions to recipients as part of
+that project, subject to preserving this permission's applicable credit and
+notice requirements. This permission is not a copyright assignment, is not
+exclusive, and does not cover unpublished work, separate repositories,
+ModCompass service operation, credentials, or content not offered in those
+pull requests. Roxas2712 retains his own rights to his contributions.
+
+For uses relying on this permission:
+
+- retain the relevant source copyright and licence notices;
+- give visible credit in the project's README or equivalent public project
+  page, and in the application's existing About / Credits view, if present;
+- use at least the following credit, or a substantially equivalent one:
+
+  > Contributions by Roxas2712 —
+  > https://github.com/Roxas2712
+
+A maintained consolidated contributor credit is sufficient; a separate
+credit on every screen or for every change is not required. Adapted
+contributions must not be attributed exclusively to another author. Other
+contributors' credits must also remain intact.
+
+## 4. Earlier licences and permissions remain effective
+
+This notice does not revoke, narrow, or retrospectively add conditions to
+any permission already validly granted, including MIT / GPL grants,
+separate agreements, or permissions arising from previously submitted
+pull requests. Where an earlier grant permits a use independently of this
+notice, its existing terms govern that use. For such earlier uses, the
+visible credit above is requested to the extent it is not already required.
+
+For subsequent contributions, this is the default statement of Roxas2712's own reserved rights and the specific PR permission, subject to any
+applicable existing licence obligations or separately agreed terms. It
+does not change another rights holder's licence or guarantee compatibility
+of a particular combination of code.
+
+## 5. No warranty
+
+To the extent permitted by applicable law, these contributions are provided
+as is, without warranty. No support obligation, endorsement, or rights to
+third-party code, game assets, names, or trademarks are granted.
