Open isle.pizza and play LEGO Island in the browser. It is built from the isledecomp decompilation of the original program files, adapted by the isle-portable project and compiled to the web with Emscripten. It is an unofficial fan project and still in development. Where the game files come from is not stated on the page.
The original game
Pepper Roni, a pizza delivery boy on LEGO Island, tries to stop the escaped prisoner the Brickster from destroying the island. Players walk and drive around a LEGO-brick island, deliver pizzas and build vehicles. It sold close to one million copies by 1999.

The browser version
isle.pizza describes itself as the classic 1997 LEGO Island, "faithfully rebuilt to run in modern browsers", with no download and no install. The page says it is an unofficial fan project not affiliated with or endorsed by The LEGO Group, and that the project is still in development.
It sits on top of two open-source projects. The isledecomp project has decompiled both ISLE.EXE and LEGO1.DLL; its repository says the result is, to the best of its knowledge, functionally identical to the originals, and that it only builds for 32-bit Windows. isle-portable adapts that code for modern systems: SDL for windows and input, the miniaudio library instead of DirectSound, and a graphics layer that supports WebGL. isle.pizza compiles it for the web with Emscripten, and the site's own code is also published.
The page opens on a menu that mirrors the original launcher (Run Game, Configure, Free Stuff, Read Me, Cancel). Browsers block sound until you interact with the page, so the intro starts muted and a mute icon turns it on. An optional offline install downloads about 550 MB to the device and later loads from there. The page does not say where those game files come from.
