Cadillacs & Dinosaurs II: The Crown Tide

An unofficial single-player fan sequel to Capcom's 1993 arcade game, made for Mostafa's next adventure. Mustapha, Jack, Hannah and Mess return six months after the first game's exact ending for six chapters, six elites and six bosses.

Fessenden died a beast in his Under World beneath the City in the Sea, the lab blew, and the flood that followed drowned half the coast. Marshal Sable, the Wassoon lawman who took the captured Black Marketeers into custody, seized the Crown dam and now sells water by permit. Every chapter breaks one link of his supply chain, and at the dam he takes the unfinished Crown treatment rather than open a gate. Fessenden stays dead. Read the story bible.

Ch	Chapter	Place	Elite	Boss
1	WASSOON · The Prison Barge	Hannah's harbour city at night, the jail quay and the prison barge	the Barge Bosun	Warden Rook, the dock jailer
2	THE CORAL CAUSEWAY · The Tide Convoy	a highway the sea gives back at low tide; the Cadillac chapter	the Tide Outrider	Haulmaster Krag, who becomes the armoured Ironclub, fought on foot when the convoy halts
3	THE VERDANT BIODOME · The Nest	a ruined glass dome on the jungle frontier, its collar pens and egg racks	Pack Alpha, freed	Headkeeper Thorne, who grafts herself into Glassback; smash her sonic driver to bring her down
4	THE SINK · The Pump Station	the one deliberate return: the flooded Under World, pumped dry for salvage	the Brood Mother	Foreman Cinder, a salvage diver with a pile driver who overloads his rig into Overdrive Cinder, then surrenders
5	THE OBSERVATORY · Dr. Echo	Echo's observatory on the cliffs, its archive and vat hall	the Mirror Test	Dr. Echo and her acoustic dish, then the Echo Engine, her four-legged sound-walker
6	THE CROWN DAM · The Crown Tide	the dam terraces, the collar pylons and the spillway	the Crown Guard's officers	Marshal Sable, the gate controls, then Crownback

In the last chapter Hannah breaks the collar pylons with Echo's key and the freed conscripts fight beside you; after the gate controls fall and the spillway opens, Sable becomes Crownback. Warden Rook, Haulmaster Krag / Ironclub, Headkeeper Thorne / Glassback, Foreman Cinder / Overdrive, Dr. Echo / Echo Engine, Marshal Sable and Crownback fight on their own generated sprites (loaded per chapter); the gate controls are still the Crown capsule bake from the ROM tiles.

Play or deploy

Open play.html (or PLAY GAME.bat) to play. index.html is the home page (home.css, home.js, the art in assets/home/ rendered from the game's own sprites by node tools/home/build-home-art.cjs); its PLAY NOW button opens play.html, PLAY WITH FRIENDS opens play.html?online (the lobby), and a ?join= share link opened on the home page is forwarded to play.html. Keep the whole folder, including assets/stages, assets/audio and assets/sfx. Offline play from file:// needs no installation, server or emulator.

For Vercel, import this repository, choose Other, leave the build and install commands empty and use the output directory . (vercel.json supplies these). There is no build step on Vercel: the generated files are committed. DEPLOYMENT.md also covers GitHub Pages.

What it is made of

Everything you see is the original arcade's own art, read from the 1993 ROM set and recomposed into new places:

• Heroes are the arcade's frame records with their own animation timing, holds and weapon placements; the empty gun is hurled at the enemy, as the user asked.
• Enemies and bosses are the original bodies with their ROM animations, attack tables and HP; the sequel's bosses (Rook, Krag / Ironclub, Thorne / Glassback, Cinder / Overdrive, Echo / Echo Engine, Sable and Crownback) have their own generated sprites (tools/art/specs), whose pixels load with their chapter.
• Stages are new layouts built from the arcade's own tiles, palettes and walkable bands (no original level is replayed as it was); the Cadillac, the food and score items, the weapons and the effects are ROM records too.
• The screen is the cabinet's: 384 × 224 arcade pixels drawn at 2× on a 768 × 448 canvas, the top HUD and the weapon panel in the ROM font at the cabinet's coordinates, chapter cards, intermission panels, the stage-clear tally and the boss cards in the arcade's presentation.
• Feel: the heroes walk at the ROM's own speeds (0x50E4, run 0x5064), the hit sparks and POW! are the arcade's records, and the soundtrack and sound effects are the supplied arcade audio.

Display. The cabinet's 4:3 picture is the default. The Sound Room's aspect button switches to square pixels (12:7) and back; the setting is saved.
