Stumbled upon this earlier while trying to find release date for Wii U/Xbox versions. It's a rom hack he made of the original metroid, programmed for the GBA in like 2002. He made it before Zero mission was out, which somehow makes it even more impressive. The sprites and animations are crazy good for the GBA, and you can really see his style in the art. Just like in AV the backgrounds have several different layers of parallax scrolling. It's cool to see how he took what he learned here and implemented it in AV.

Dunno if this fits the speedrun forum, but I thought you guys would be interested.

Dude I'm late to the party but fuck this is amazing!
