Licensing issues and unrelated[edit]

RISCOS Ltd said on their website: "We await the full details of the licensing terms and conditions that will be applicable to RISC OS 5 source code. When these are known we shall be able to review the situation. However the current expectation is that there are very few features that are present in RISC OS 5 that are missing in RISC OS Six, that have a very high priority for inclusion in future releases of RISC OS 6."^[1]

Managing Director Paul Middleton told Drobe News that the company would not be open sourcing its OS code in the same way.

He said: "It is probably worth pointing out that the 'open sourcing' of RISC OS is going to solely cover RISC OS 5 versions. We do not intend to 'open source' RISC OS 4 versions as some people seem to have assumed."

"I would point out though that we have always been happy to work with developers who require source level access to RISC OS, in the same way that Acorn made sources available for particular projects. The difference between us and ROOL is that we do require any changes made to be fed back to us, as we only want one version of RISC OS 4 to be available." ^[2]

An Iyonix-compatible version of RISC OS 6 is described as a possibility. From the RISC OS 6 FAQ : "Some people have assumed that because we have not made any definite announcements with respect to Select 4 on the Iyonix, that we are not interested in doing the work. The facts are however that our resources are limited, and priority has been given to working with partners who actively want RISC OS Select features on their products."

RISCOS Ltd and ROOL have agreed to cooperate, but expect to continue working on their own forks of the source tree.^[3]

More recently however, concern has been expressed concerning the exact licensing terms and ownership of RISC OS, with some commentators claiming that recent efforts to port RISC OS to platforms other than Iyonix might not be permitted.

RISCOS Ltd and Castle continued maintaining separate development branches of the RISC OS operating system for some time, but as a result of a lengthy dispute over licensing during 2004^[4] the two companies agreed to merge the two competing streams.^[5] After taking over development from Castle, RISC OS Open Ltd later distanced themselves from this announcement, indicating it was technically impossible^[6] but indicated^[7] they would work together to smooth incompatibilities.

Some pieces of software famous to other platforms such as Microsoft Windows and Linux have been ported to RISC OS, most notably Firefox^[8] and Thunderbird.^[9]

RISC OS Emulators[edit]

This is a list of the emulators that are capable of running RISC OS, I think I've got all of them. I've decided not to commit this directly to the RISC OS article as due to being involved with two of them it is a conflict of interest. However if someone thinks that they're NPOV enough please add them to the page. If there is not a wiki page yet for an emulator it links to the emulators homepage. Also note that the emulators listed at http://en.wikipedia.org/wiki/List_of_computer_system_emulators#Acorn_Archimedes has many issues, not least that many listed are not system emulators.--Flibble (talk) 11:43, 15 February 2013 (UTC)
