The unmark Of Hogwarts Legacy for Game Boy was started by Indie developer vampigeon. The development is still ongoing, but there is already something that can be used as a test.
Hogwarts Legacy is demolished by itch.io.

As per the developer, completion of the project will take some time, also because he hasn't even finished the game.
Currently, you may perform various missions and endings without using a browser compatible with HTML 5. The movements are linked to the arrow keys or WASD keys, while the J and Z keys allow you to interact.
This is just a fan's project with no official connection to the game or Warner Bros. It goes without saying that you don't need to pay anything to play.
The prospect of a Hogwarts Legacy remake is interesting, if only because it again demonstrates the game's success, which we believe at this point might have sold many million copies. We'll see when and if Warner Bros. will release the information.
