RISC OS 5.18 released
RISC OS Open have announced the release of their latest stable release of RISC OS, version 5.18 to be precise. This update features no less than 340 improvements since the last official release and has been officially vetted by Castle Technology for the Iyonix PC and R-Comp Interactive for their ARMini.
The new ROM image should be able to upgrade all versions of RISC OS from version 5.07 or later and is provided with a flash programming tool (for Iyonix users), which also takes a backup of the previous version just incase you wish to go back.
The OMAP3 (i.e. ARMini) version of the operating system now supports hardware CMOS memory fitted on a carrier board plugged into one of the headers on the motherboard. This permits saving of common configuration settings which will be retained when the power is off. CMOS memory carrier boards are available now from the ROOL store and are suitable for use on the original Beagleboard, Beagleboard-xM, and Pandaboard.
As the ROMs now several new modules, some of the module location numbers have changed. Because the *UNPLUG settings only remember the module location numbers you may need to review any unplugged modules after the upgrade to ensure the desired ones are unplugged, and that crucial modules are not left unplugged by mistake.
For the full release notes and download/installation instructions, please see the ROOL press release.
Raspberry Pi released
The Raspberry Pi Foundation have launched their much anticipated, and dirt cheap computer, the Raspberry Pi. The machine is currently being sold through a number of electronic retailers, namely Farnell, RS Components, and Allied Electronics. However overwhelming demand for the device means that it may take a month or two for production to ramp-up and all backorders to be filled.
The Raspberry Pi is a single-board computer developed by the Raspberry Pi Foundation. The foundation plans to release two versions, priced at £16 and £22. The Raspberry Pi is intended to stimulate the teaching of basic computer science in schools and has been designed for use with the Linux operating system, although a port of RISC OS to the machine is already underway.
The design is based around a Broadcom BCM2835 SoC, which includes a 700MHz ARM1176JZF-S processor, VideoCore IV GPU, and 256 Megabytes of RAM. The design does not include a built-in hard disk or solid-state drive, instead relying on an SD card for booting and long-term storage.
MPlayer ported to RISC OS
Chris Gransden has ported the popular cross-platform media player and encoder MPlayer to RISC OS, this significant advancement means that RISC OS can now fully play MP4 and other mainstream video formats.
Chris’ port is a direct build of the Linux sources and does not feature much RISC OS integration as of yet. It makes a good attempt at playing most MPEG, VOB, AVI and WMV formats, plus many others. You can expect reasonable frame rates up to 480p resolution on recent RISC OS hardware which currently includes Beagleboard and Pandaboard based machines.
Bundled along with the MPlayer download is MEncoder, which is a simple movie encoder, designed to encode MPlayer-playable movies.
You can download this latest version of MPlayer from the riscos.info website here.
Version 3.38 of OpenVector, OpenGridPro and DrawPlus has been released. These applications are all open-source enhancements to Draw, providing enhanced layering and object library capabilities as well as the ability to draw advanced grids and other object layouts. This release features improved compatibility with Cortex-A8 hardware such as the ARMini and BeagleBoard. Compressed drawfiles and libraries can now be loaded when alignment exceptions are enabled. Consistency of layered merging has also improved.
Version 1.71 of PlayIt, a disc-based engine for playing sound samples, has been released. It is used as a resource by several audio players including DigitalCD. This new update contains no new functionality but several significant bugfixes, increased 26/32bit neutrality, and changes for ARMv7 compatability.
BarFree from Bernard Veasey has been updated to work on RISC OS 5.18, BarFree copies revised ‘Messages’ and ‘Templates’ files to your ’PreDesk’ directory within its own directory called ‘Free’ to enable different style Free Space windows.
Charm has been updated to version 2.5.3 to add support for 'new' and 'delete' keywords for allocating and releasing storage for records. Charm is a high level programming language with a compiler than generates efficient code with a small memory footprint.

As you may or may not already know, over the past few weeks I've been working on improving the performance of RISC OS 5's USB mass storage drivers. Although RISC OS Open
have yet to make an official announcement about the availability of the drivers, they are in fact available for download now from the ROOL website.
Read on for some brief benchmarks, and instructions on how to install the drivers on your Iyonix.

As most of you probably know by now, a few months ago I started work on porting RISC OS Open's RISC OS kernel to TI's OMAP3 platform - a group of SoC's (Systems on a Chip) which use ARM Cortex-A8 cores. To date, OMAP3 SoC's have been confirmed as being used in various products, including the Pandora
handheld gaming console, the Touch Book
convertible netbook/tablet, and the BeagleBoard
development board. For years RISC OS users have been asking for a new portable RISC OS machine, and soon they may find that they have several available.

| 1 comment in the forums
A while ago you may remember that I wrote an article about video conversion for RISC OS
, and near the end raised the topic of video conversion on
RISC OS using a port of ffmpeg
. Although the version of ffmpeg I originally tried on RISC OS was old and broken, Christopher Martin obviously thinks there's some merit to this approach, as he has recently produced !FFmpeg
, a working port of ffmpeg for RISC OS.
Once more in the interests of SCIENCE, I threw a few test videos at !FFmpeg and measured its performance against that of a similar version of ffmpeg running on my Windows PC.

If you've got a lot of TV programmes or other video clips on a PC, chances are you'll be wanting to be able to play them on RISC OS as well. This article will explain how to use free tools to convert them to a suitable format for playback on RISC OS. Furthermore the process can be fully automated, so is ideal for processing large collections.

A port of Firefox 2 for Castle
Technology's IYONIX PC
has been released by Peter Naulls. This release comes after users contributed the 1000 GBP that Peter had asked for to fund the development.
Peter would like to thank all those who contributed, but he is still after another 4000 GBP to release a further update with integration to RISC OS, and fixing some other issues. This release is targeted for Christmas day if the contributions meet the target.
A port for Advantage Six's A9home
computer has not been ruled out subject to financial interest, and Peter is asking people interested in a port for any RISC OS platform to email him. Update:
Rob Kendrick has released a patch
that allows the IYONIX Firefox port to run on the A9home by providing emulation for the XScale-specific instructions to a fudged copy of the Firefox executable. Link:

News just in, Mozilla Firefox 2 is now working on the Iyonix and may be ready for release quite soon!
As before, donations totalling Â£1000 are required to fund the work that has been required to release this version which may lack HTTPS support.
This new version is apparently a bit faster and more stable than the last release (Firefox 1.5b5)
Also, subject to an extra Â£4000 funding on top of the above, further development can also be secured to give full RISC OS integration, including:
- Unicode fonts
- plug-in support
- RISC OS widget usage (?)
- Speed improvements
Lucky Iyonix users!
An A9 version is also being considered depending on the level of interest.
No other version is currently planned.
Full details can be found on the Firefox page
at the RISC OS.info

Once again it's time for the Wakefield show, the 11th one to be exact. Just for you lucky punters, roughly 30 exhibitors will be attending the show this year, and as usual the theatre has a packed programme throughout the day. In addition to this, there's also a "RISC OS in action" section, manned by Ian Chamberlain and sponsored by Qercus, which will have a number of demonstrations of RISC OS in use on A9 and Iyonix computers doing various tasks.
Exhibitors this year include Castle Technology, Genesys Developments, MW Software and the NetSurf development team, who will be demonstrating the latest developments on the open source browser.
VirtualAcorn will also be present, demonstrating their latest addition to their product family, VirtualRPC-SA, which provides emulation of the StrongARM processor in addition to the Arm710 processor it previously supported.
The theatre programme for this year's show is as follows:
|10:45||Advantage6 - Part 1|
|13:00||Paul Middleton - RISCOS Ltd.|
|15:00||Advantage6 - Part 2|
Parking at Thornes Park Athletics Stadium is free, and entry to the show costs £6, with under 5 year olds getting in free (I'd imagine that's physical age, not mental age!) The show is open from 10am until 5pm on Saturday 13th of May.
If you're going to the show this year and would like to share your thoughts of the show with us, please get in touch!
