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!

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:
