[13] In 2009, author Adrian Lees[14][15] posted on The Icon Bar, showing an early prototype of the software running on the BeagleBoard.

[15][16] Progress on further compatibility for the Raspberry Pi single-board computer was announced by Lees on the RISC OS Open forum in 2012.

It employs an XScale-optimised ARM code interpreter, supports SWI emulation from RISC OS 4 to 5, flag preservation and creation of dynamic areas in low memory.

[20] As of 2003[update], due to the memory remapping employed, native 32-bit applications are restricted to a maximum size of 28Mb while Aemulor is running.

[22][23] Aemulor Pro adds support for low-bpp screen modes, sound, hardware emulation of VIDC/IOC, an altered memory map and 26-bit filing systems.
