LEGOLAND (Windows, 2000) running in a modern browser, built from the matching decompilation in brickpark-decomp and modelled on isle-portable. The front end, all five tutorial lessons, free play and the campaign levels play.

You need your own copy of the game. Neither repository contains game data or binaries, and a build packs your game files into its output, so never publish or share a build directory.

• Your LEGOLAND CD, or an image of it (.iso or .bin). The disc holds the installer archive main.z, the three .res volumes, Speech/ and directx.cab.
• Emscripten 6.0.9 (the version the tree is built against), CMake, Ninja and Python 3.
• Optional: ffmpeg on the PATH, so the build can decode the advisor's video clips; without it the advisor's panel is plain. Node.js runs the tests.

git clone --recurse-submodules https://github.com/adamXbot/brickpark-browser.git
cd brickpark-browser

# 1. Game files: the CD's contents in gamedata/disc, the installer archive
#    extracted to gamedata/main, and the game's executable in original/.
mkdir -p gamedata original
cp -R /Volumes/LEGOLAND/. gamedata/disc/
python3 decomp/tools/iscab.py extract gamedata/disc/main.z -o gamedata/main
cp gamedata/main/legoland.exe original/

# 2. The player page.
emcmake cmake -S . -B build-wasm -G Ninja -DCMAKE_BUILD_TYPE=Release -DLL_ILP32=ON
ninja -C build-wasm legoland_web

# 3. Serve it locally and open http://localhost:8080/
python3 -m http.server -d build-wasm/web 8080

main.z sits on the CD (find gamedata/disc -iname main.z if the disc's layout differs), and the executable it unpacks is the one the decomp README names by SHA-256. The build packs gamedata/ into build-wasm/web/data/ for the page's own download; that folder is the game's files, for your computer only.

The page opens on its menu. Game files installs the game into the browser once, either from the pack the build just made (Download) or from your own disc: drop an .iso or .bin, a .zip of one, a copied CD or an installed LEGOLAND folder onto it. Everything is read and stored in the browser; nothing leaves your computer. Then Play.

• The game's cursor follows your pointer at any window size. The toolbar has sound, full screen and Leave.
• Saves live in your browser. Saved games lists players and parks, and exports or imports them as a zip laid out like the game's profiles\ folder.
• Options → Extras → Free Play with everything opens free play with every item unlocked. It is off by default and writes nothing to your profile.
• Music plays on the developer page below, which preloads the instrument set the build extracts from the disc's directx.cab. The player page does not install the instruments yet, so its music is silent for now.

ninja -C build-wasm legoland_browser     # legoland.html: the instrumented page
python3 -m http.server -d build-wasm 8968   # open http://localhost:8968/legoland.html

cmake -S . -B build -G Ninja && ninja -C build   # native: every source with clang
ninja -C build legoland_linkcheck && ./build/legoland_linkcheck
ctest --test-dir build --output-on-failure       # or --test-dir build-wasm

The developer page names traps, hashes frames and runs replay scripts; its version cell links the commits the build was made from. The native build is a symbol census and a test host rather than a playable game, because the recovered code is 32-bit and only wasm32 keeps its layouts. -DLL_FAITHFUL=ON builds without the documented fixes to the shipped game's own bugs (QUIRKS.md).

Everything else, from the build options and the layout of the tree to the tests, CI and the lane-by-lane log of how the port was made, is in docs/DEVELOPMENT.md.
