Right after Wandoos 98 is unlocked, there is a 24h installation period (only works online). After the installation and at each rebirth, there is a 1-hour boot up process for Wandoos to reach its maximum speed. It is not necessary to be online for the booting process. The speed increase is linear, and ranges from 0-100% speed. Wandoos 98 remains unlocked throughout rebirths but the booting up process will be reset at each rebirth.
