After Zelda fans theorized wildly on the source of this Breath of the Wild Nintendo DS demake, the original creator has come forward: "it's so funny seeing people speculate about this"

Sorry to break the news, but if you've been wildly speculating on the origins of a certain Legend of Zelda: Breath of the Wild demake that made rounds on Reddit and Twitter recently, the mystery has a far less juicy culprit.

"It seems an old ROM of a project I was working on with friends leaked online," creator Ermelber quote replied on Twitter in response to a GBATemp article.

Found on an old DS flashcard purchased on Chinese commerce platform AliExpress, the ROM file reimagines Breath of the Wild as a pixelated DS game. Reverse image searches revealed that clips of the demake were first published on Chinese DailyMotion-like site BilliBilli in 2019, though the poster of said videos (as well as the identity of the ROM creator themselves) was a total mystery. This layer of intrigue left plenty of room for self-proclaimed internet detectives to work their magic, coming up with a host of theories of varying levels of extravagance.

YouTuber JustJasen posted a detailed deep-dive into the demake, linked above, where he speculates the creator as being based in China. This could have made sense, given how both AliExpress and BilliBilli are Chinese-based companies and that BilliBilli is relatively unknown to Western audiences. When Ermelber, an Italian modder and game developer, claimed the ROM as his own person project made with friends,
