In Harry Potter and the Chamber of Secrets, Harry and his friends unravel the mystery behind the Heir of Slytherin (yes, it's Lord Voldemort, duh) and his Chamber of Secrets. USTA2877 would make short work of that, but is frequently interrupted by senseless (unskippable) cutscenes and loading screens, which this game (series) is somewhat notorious for. Most of this run is relatively glitch-free, so lean back and enjoy a fast-forward through the second part of the Harry Potter series.
Note: The minor audio and animation glitches are caused by bugs in Dolphin's emulation and capture.
