The original Diablo with the Hellfire expansion can now be played in any browser on any computer. The game has good optimization and full control support. This was reported by ArsTechnica.

This was made possible by an open source project published on GitHub called Diabloweb. Now the publication of the project in X is also actively gaining popularity.

In the README file of the new project, developer d07RiV says that the game was launched in a browser thanks to another open source project, DevilutionX, which aimed to optimize Diablo for modern systems.

“I’ve modified the code to remove all dependencies and exposed the minimal required interface with JS, allowing the game to be compiled into WebAssembly. Event handling (especially in the menus) had to be modified significantly to fit the JS model,” writes d07RiV.

To start the game, you need to launch the website, download the game file, and start playing. If you simply open the website, players will be able to access a shareware version of the game, but it will be incomplete.

To get access to the full game, you need to own a physical or digital version of the game, which can be purchased on GOG, and extract the DIABDAT.MPQ file from it, which you should then upload to the site.
