Prior to becoming the head of Climax Studios (then The Climax Group), Rockett mainly dealt with music and sound effect creation for handheld titles (particularly those for Game Boy Color), including ports of older games. Two of these ports were the GBC version of Street Fighter Alpha and the GBA version of Street Fighter Alpha 3↑, both of which have rather infamous soundtracks due to how they were compressed in adherence to their respective system's design limitations. Other titles Rockett worked on include X-Men: Mutant Academy, MotoGP '06 and Split/Second.
