Desert Strike — original assets, terrain and palace finale v0.5.0

Original game artwork and music, reconstructed terrain, and the palace escape sequence for the standalone browser/offline recreation.

• Original DOS sprite sheets and terrain tiles from DarkWolf's Spriters Resource collection; eight Mega Drive music tracks from the supplied Internet Archive collection.
• Four terrain grids matched against the Genesis map references, with campaign-specific palettes and coast boundaries.
• Palace escape vehicle, copilot transfer, bomber boarding, breach and rescue.
• Corrected final-campaign radar defenses and hidden extra lives.
• Fixed 60 Hz simulation across display frame rates; civilian penalties, bonus rescues and an itemized score report.
• Copilot selection, tactical-map filters and the mission-rule improvements from v0.4.
• Updated README, campaign guide, fidelity ledger, build instructions, verification record and asset credits.

Validation: 49 passing simulation tests, all four campaigns completed through browser keyboard/pointer input, desktop/mobile interaction checks, and embedded music playback. The built HTML also launched with every subresource request blocked. A fresh direct-file launch is not claimed; see VERIFIED.md for the exact scope.

Extract Desert-Strike-offline.zip and open Desert-Strike.html, or use Play.cmd on Windows. Artwork, music and code are embedded; no ROM or emulator is required.

This is not a verified 1:1 port. Dynamic-object placement, original numeric scoring, flight/combat coefficients and event timing remain estimated. Complete original cutscenes and passwords are absent. The artwork is from DOS and the music from Mega Drive. See the fidelity ledger.

Original assets are separately credited in THIRD_PARTY.md and are not covered by the code's MIT license.
