This is a very misleading article. This isn’t an emulated GBA running in Minecraft. This is a replica of a GBA game running in Minecraft. There’s a very significant difference here.
ETA: I don’t want to take away from the work that was done here. It was clearly a massive amount of work. What’s annoying is I keep reading “this guy emulated a GBA in Minecraft” when they really didn’t – there’s no GBA hardware emulated here. What this person did was load textures from the original game and is basically reimplementing the entire game within Minecraft. That doesn’t make this any less cool – don’t get me wrong, but it’s like me saying I’m “emulating a PDP-10 in a web browser” because I rewrote Zork in a set of HTML pages.
