Here’s the takedown notice posted by GitHub:
Nintendo requests that GitHub, Inc., disable public access to the website at http://jsemu.github.io/gba/. This website provides access to unauthorized copies of Nintendo’s copyright-protected video games and videos making use of Nintendo’s copyrighted Pokémon characters and imagery in violation of Nintendo’s exclusive rights.
In total, Nintendo identified more than 20 games including numerous titles from Pokemon, Metroid, Super Mario Advance and Legend of Zelda franchises that it believes are blatant copyright infringement.
There are a few websites that allow dedicated Game Boy Advance fans to play old console games through browser-based emulators. But despite fan interest in such nostalgia projects, Nintendo has largely been less pleased with user-made initiatives.
Back in 2008, the company brought suit against homebrewers who make and sell DS carts illed with old, pirated games. Most recently as of March, Nintendo issued a takedown notice to Cloudfare asking it to deny access to a browser-based version of Super Mario 64’s first level.
After receiving the takedown notice from Nintendo of America’s legal representation, GitHub has shut down the Game Boy Advance emulator with dozens of pre-loaded games. Which means if you’re a nostalgic Game Boy Advance fan, it’s time to set up your old consoles again or find another way to take a trip down the memory lane.
