I've just got my Model-B and tried the 5.19rc6 image which seems to work well (faster than Raspian and LXDE by a mile!) but I left the RISCOS scene around the time the Iyonix came out, with some limited playing with Select4 in emulators, so am a bit out of touch.
Anyway I was just a bit confused by the need for Fat32FS when RISCOS has been able to read/write FAT32 since 3.1, is it to do with USB perhaps - something which didn't even exist on my RiscPC.
I was pretty surprised my Assembler programs still ran - I guess 26-Bit ARMv4 isn't that different to 32-Bit ARMv6 after all eh ROL? What are the requirements for "regular" programs, do they have to be 32-Bit versions or just neutral or what?
Lovely to see my BASIC WIMP programs running too, after setting the filetypes - they were tarred up on Linux by mounting the disks using rpcemu a few years back!
On a related note - what happened with the RISCOS split - did Select6 ever go anywhere, the A9 (A6?) got canned IIRC, and I thought the Iynoix got canned too, so is RO5 now opensource and not a Castle product anymore? Does ROL exist anymore?
