Moving back to Linux RPCEmu on my Mac www.iconbar.com/articles/Mov... I'm a big fan of RPCEmu which provides an excellent RISC OS environment on my Mac when I'm travelling. In this post I'm going to explore why I have switched back to the Linux version and cover some of the issues I encountered.

Here is an article with all the details about a new chunk of progresses on #UltimaVM and the new project's mascot Luma. Still lots of work to finish to get the first beta release out, but hey I am moving forward! paolozaino.wordpress.com/2025/11/09/u... #RISC_OS #riscos #Linux #Windows #macOS #BSD

I've just uploaded an update to my RISC OS !RMA utility, primarily to fix RO3 compatibility (thanks to Phil Pemberton for the report) but I noticed I hadn't released the previous version that featured an important upgrade - the ability to explore ANY Heaped Dynamic Area. So, a useful update:

I've finally finished pimping my David Braben-signed BBC Micro B+, and it can now run more variants of Bell & Braben Elite than any other contemporary machine ever. The #BBCMicro B+ is officially the Commander-in-Chief of #8bit #Elite. 🫡 See thread for details. (1/8) #retrogaming #retrocomputing

PhotoDesk 3.25 released www.iconbar.com/articles/Pho... It has clearly been a very busy few months at R-Comp... And they have found time to squeeze in a new version of PhotoDesk.

I am so lucky to get to talk about things I love in Computerphile! Old hardware, cool encoding, prog rock and folks also spotted some Easter eggs in the background :) youtu.be/VEyVm6dU55c Very fortunate to get these opportunities; hope I can find time to keep doing after I start my new job!

That's the one!

'the hell? it's 4:36am... lol anyway, new UltimaVM PUSH/POP register range fast memory copy is done and there is also a little "twist" POP supports both strick LIFO (like the JVM) and natural order (like the ARM). Had to finish so late, because I had a hell of a busy day at work... Need some sleep!

I've been working on Ovation Pro to add extra scaling options to the picture proxy setting. For those who attended my @rougol.bsky.social talk, I explained the use of proxy images. Base/16, Base/32 & Base/64 now offer even smaller proxies, making for smaller document sizes. #OvationPro #RISC_OS #DTP
