Official free download vs open-source retro game: which rights evidence is stronger?
Neither label is automatically stronger. An official free-download page may authorize use only from that host, while an open-source repository may license code but omit art, audio, trademarks, or binaries. Choose only after recording the exact artifact, rights holder, allowed acts, asset coverage, host boundary, and review date.
Do this in order
- 01
Identify the exact binary, source tree, game data, artwork, audio, documentation and trademark involved.
- 02
Open the creator or rights holder's first-party page and record its date and scope.
- 03
For a free download, record approved host, use class, redistribution and modification terms.
- 04
For open source, confirm the license file applies to the release and separately inventory every asset.
- 05
If redistribution or asset coverage is unclear, link only to the approved first-party page and do not mirror.
- 06
Keep the rights receipt separate from checksum, malware scan and emulator compatibility evidence.
Decision and diagnostic table
| Evidence | Can establish | Cannot establish alone |
|---|---|---|
| Official free-download page | Stated download/use scope | Public domain or mirroring |
| Source-code license | Rights to covered source | Rights to every asset/binary |
| Repository notices | Attribution and exceptions | Trademark permission |
| Technical audit | Identity/compatibility | Copyright permission |
Free describes price or scope, not ownership
MAMEdev's free-ROM index preserves a non-commercial and approved-host boundary. That is useful permission, but it is not a public-domain declaration.
Open source still needs an asset inventory
A repository can combine licensed code with assets under different terms. Verify the release artifact and each non-code category before hosting.
Use the narrow safe action
When the first-party page clearly permits downloading but not redistribution, an exact page link preserves the source boundary without creating a mirror.
This is a conservative publication workflow, not legal advice. Unclear scope means ArcadeShelf should not host, bundle, modify, or redistribute the artifact.
