Welcome to my Matoran Adventures homepage!
Several years ago, a pseudonymous Argonaut developer shared partial source code for the 2002 Game Boy Advance game Bionicle: Matoran Adventures. I'm a little bit of a GBA guy, so I immediately dug into the code trying to see what I could find. I made pretty good progress on converting the graphics data back to images, but life got in the way before I could do a thorough enough job that I felt comfortable sharing.
Of course, the downside to not sharing your work is that you start to feel ridiculous sitting on a hoard of secret bionicle sprites. And so, basically every time Matoran Adventures has come up in the last five years, I've felt little pangs of... not guilt, but "oh yeah, I still need to get around to that".
So here's me getting around to it! Presented on this site is every image in the game, and more besides. Have fun looking around, and let me know if you have any questions!
