Since the opening up of the RISC OS source code, developers have been experimenting with the OS on modern ARM hardware. Recently, work has progressed on porting some vintage Acorn games to other platforms, including iOS and Windows. Paradise Games has released an iOS port of Inferno, and TBA Software has rendered BHP in OpenGL on Windows. TBA has also ported its TBAFS filing system to ARMv7 hardware and is investigating its TAG games engine and the modernisation of BBC BASIC. The Icon Bar has further details.
