B OS
From Progressbar95 Wiki
B OS is a special system added in the update 0.98. It is based on BeOS. The system has two versions:
- PC kernel, accessed from the PC menu
- BC kernel, accessed from the Progress menu
There are no major differences between the two versions, though progress is separate between each version. To unlock B OS, you must collect 3 million points in BarOS after unlocking BAR/X.
