Adobe only provides an outdated version (11.2) of its official player for Linux on IA-32 and an AMD64 developer preview release in a binary-only form. Gnash, however, can be compiled and executed on many architectures, including x86, ARM, MIPS, and PowerPC. It also supports BSD-based operating systems. An early port for RISC OS, which has never had Macromedia/Adobe Flash support beyond Flash 3, does exist, as well as an early port for BeOS, where Flash support terminated at Version 4. Development of a port to AmigaOS 4.1 has also begun. A port to the Haiku Operating System also exists.
