Original games and content

The original games, names, trademarks, artwork, audio, dialogue, and other original content belong to their respective rights holders.

You must provide your own lawfully obtained game files. This website does not provide the original game archives or game downloads. Your selected files are read locally in your browser and are not uploaded or overwritten by this page.

Visitor statistics

This website uses Cloudflare Web Analytics for basic visit and page-performance statistics. It does not use analytics cookies or track gameplay. Game files and saves remain in your browser.

Bitmap lettering

The engine embeds the games’ original bitmap letterforms because their font data uses the .SYS extension, which some browser folder pickers block. These are raster glyph images, not the games’ original executable font-generation code.

U.S. copyright regulations exclude typeface as typeface. The U.S. Copyright Office distinguishes letterforms from copyrightable software that creates or uses them in Compendium section 906.4. This project relies on that typeface/software distinction for its bitmap lettering; it does not claim permission under every jurisdiction or for other game content.

Restoration and rendering corrections

Other graphics, recordings and gameplay text are loaded from your game files. The engine includes small restoration edits and computed selection and lighting corrections based on those assets.

Permissions

This notice does not grant permission to copy or redistribute original game content, and is not a claim of legal approval. Owning a copy does not itself grant redistribution rights.

For EA’s published guidance, see EA’s content policy.

Engine software

No third-party software license text or attribution notice is required to accompany this engine distribution. Rights in the original games, user-provided game files and firmware ROMs are unaffected.
