OpenConche：为2007-2009年Chocolatier游戏打造的现代引擎

A modern, open source, cross-platform engine for running Chocolatier, Chocolatier 2: Secret Ingredients, Chocolatier: Decadence by Design.

Between 2007 and 2009, Big Splash Games released Chocolatier and Chocolatier 2: Secret Ingredients (published by PlayFirst), and Chocolatier: Decadence by Design. You can still buy Chocolatier: Decadence by Design on Steam.

However, the games are showing their age; on modern macOS you can't run them anymore, and on Windows I had some issues with unsupported display drivers and monitors, e.g. when using Steam streaming. When the game does run it doesn't look the best, the game is rendered at 800x600 resolution and then optionally scaled to fullscreen.

This project allows you to run all three games on modern platforms, and renders natively at any resolution. The game art is only available for the 800x600 resolution so is still scaled up, but the text renders at your native size, much improving the overall look.

OpenConche is just the new engine, you still need the original game assets in order to play.

This is a hobby project, published as-is. It was built in a few weeks of AI-driven development against the games' own binaries and scripts, with the reverse-engineering record kept alongside the code so that the reasoning behind every decision is checkable. It is released so that it exists somewhere public:

The fonts render at the real window resolution, here at 2x, while the art stays 800x600:

Your own copies of the games. The engine finds the assets in your installs (Windows assets/, the Mac Contents/Resources/assets/, or one level down) or takes an explicit --assets path.

Play

Download a build from the Releases page (or build it yourself: see BUILDING.md) and launch the executable.

Running openconche without --assets first shows the game finder: a launcher screen rendered by the engine itself, where you can start any of the games you've added. Click Add game and pick the game's install folder in the OS folder dialog, and the engine does the rest. Added games are remembered in the engine's own config, OpenConche/games.cfg under your user folder (%APPDATA%, ~/.local/share, ~/Library/Application Support), and the last one you played starts automatically next time. In game, Ctrl+Shift+G (or clicking the OpenConche badge that shows up on launch for a short while) opens the finder again to switch games.

On macOS the app is not signed with an Apple developer certificate, so after downloading, macOS will say it is "damaged" or "cannot be opened". Clear the quarantine flag once, in Terminal, from the folder you unzipped it to:

xattr -dr com.apple.quarantine OpenConche.app

Then double-click OpenConche.app.

On Linux, the folder dialog needs the desktop portal or zenity (Ubuntu: sudo apt install zenity).

Each game keeps its own players and saves, separate from the original game's. Chocolatier 3 and Chocolatier 3 Reforged have different content, so a player created in one won't appear in the other.

Will it run other PlayFirst games? It could, but I’m not going to add support myself. The three Chocolatier games are the only targets, and nothing else is planned.

The engine implements the parts of the Playground SDK used by those three games, so it could provide a good starting point for porting another game built on the same SDK (e.g. Diner Dash 2 or Dream Chronicles). However, this doesn’t mean those games will work out of the box. You’d still need to implement the game-specific code, and potentially extend the engine with SDK functionality that Chocolatier doesn’t use. The per-game modules in src/games/ are where that work would go (see docs/design/engine-and-games.md). You’ll have to fork the project and bring your own AI agent :)

Chocolatier, Chocolatier 2: Secret Ingredients and Chocolatier 3: Decadence by Design were created by Big Splash Games and published by PlayFirst. All original material belongs to its rights holders; this project doesn't distribute any of it.

The engine's own code is released under the MIT license (LICENSE). The two third-party files, stb_image.h and stb_vorbis.c, are public domain.

Chocolatier: Decadence by Design Reforged is Michael Lane's work and a great effort adding new life to the game!
