I can't find any other games he's made. A book called Power-Up says this about him:
NOTE: May be sloppy. Kind of just copying it without proof reading
"Born in Nagano prefecture, Aonuma was offered admission to the General Design program of Tokyo National University of Fine Arts and Music, a prestitious school founded in 1887. In that program, students get an all-around education in various aspects of design. They learn the history of design and practice their drawing, model-making, and communication skills. Through this general education theydiscover their own areas of special interest, finally drawing upon their accumulated knowledge for a final graduation project.
"Initially", Aonuma says, "I didn't think about designing games, because they weren't as popular as they are now. I wanted to do advertising design at first. But in the process of my studies I discovered that I was more interested in three-dimensional art, something with volume." For his final project, Aonuma created his own karakuri ningyou, Japanese traditional mechanical dolls that date back to the 18th centruy. Karakuri ningyou are fitted with intricate clockwork mechanisms that make the dolls move, turning somersaults, performingmagic tricks, serving tea. THey were the expensive play things of the fuedal lords and rich merchant class.
Aonuma interviewed with Nintendo right out of college and brought his dolls to show Miyamoto, unknowingly replicating Miyamoto's own interview experience in which he brought whimsical toys and creations to Yamauchi's office and was hired based on that talent. "Miyamoto really like them",says Aonuma. "In fact, that might be the reason I was hired." Miyamoto and Aonuma soon discovered another shared love: music. Aonuma is a percusionist, Miyamoto plays guitar. "If you listen to that Wind Waker title music," Aonuma tells me, "You can hear Miyamoto's own mandolin." ONe imagines late night jam sessions during gamedeadlines - or perhaps not, because Aonuma is also as serious about his work as Miyamoto.
Having learned two-dimensional design at school, Aonuma was set to draw the dot-graphics for some lesser known Nintendo titles. THe first was Mario Open Golf for the Famicom; Aonuma drew the main character animations for computer and player characters. His first project as director was an adventure game called Marvelous: ANother Treasure Island for the Super Famicom. An adventure game with action elements and Tom Sawyer-inspired cast, Marvelous was never released in the US. After that, he was assigned to assist in international third parties on their Nintendo 64 projects, while he directed the enemy and dungeon design for Zelda: Ocarina of Time on that system."
So, nothing about what he did other than Open GOlf and Marvelous. It does mention assisting international third parties on Nintendo 64 games, which is interesting but unfortunately we have no idea which games he helped with. Still a nice read from the book if you're interested in him.
