The history of O2Mania is marked by a significant split. The original creator, FancyZero, ended official development with version 1.2.0 in 2005, followed by a buggy beta of 1.3.0. In 2009, other developers known as "蜜蜂" (Honeybee) and "樱花" (Sakura) took up the mantle, creating a new lineage of versions starting from 1.4.0. This collaborative effort aimed to fix long‑standing bugs and modernize the simulator. Version 1.4.2, often called the "Christmas version," is the culmination of this collaborative work. This is why it's often referred to as an "unofficial" version—it wasn't created by FancyZero—but it remains the most advanced and stable release of O2Mania available.
