While the goal of Haiku R1 is to maintain binary compatibility with BeOS R5, there are some programs that use Private API and Private data members that Haiku will not be supporting.
This page will list those titles, and where available a working versions
- BeOS R5 FileTypes
- SoundPlay (anything newer than v4.73)
- Civilization: Call to Power (#2363)
- Personal Studio 1.5 (crash on startup...)
- R5 SerialConnect (working towards a replacement)
