On First screenshot: Beagleboard runs RISC OS 5 desktop:

It may be best to enable alignment checking in the coprocessor (CP15, c1; A bit) and then fix up unaligned load/stores in a data abort handler to maintain compatibility with precompiled binaries; Norcroft certainly does(/did) use unaligned LDR to access 16-bit quantities and this sort of behaviour change can lead to obscure bugs that are very difficult to track down.

On RISC OS 5 spotted running on RPCEmu:

I did get the mouse working....you need *Configure MouseType 0 for quadrature (I didn't recall the correct number at the time). Also noticed the 8MB + 0MB VRAM limitation, which is quite possibly a quick kludge for bring up. The CLZ instructions are readily apparent looking through the ROM image; a quick perusal revealed nothing more, though I may have missed something else by rejecting it as data.

On RISC OS 5 spotted running on RPCEmu:

For anyone wanting to try out the ROM on a physical RiscPC, you'll need to remove your VRAM expansion, if present, and modify the 'Ask' utility in the download to (i) ensure that you have CLib 5.46(?) or later loaded before invoking 'SoftLoad' and (ii) use the filename of the actual ROM image downloaded from the site.

After that, my findings are pretty much the same as Tom's...that you can boot to the desktop (although I've not got the mouse working yet), with 8MB DRAM recognised/used, but hardware scrolling is not working, probably because Tungsten doesn't actually use 'true' hardware scrolling, and I'm guessing the previous code is either broken or not properly reinstated.

Overall, very promising.

On Click right on with RISC OS:

A few of the more obscure ones:

Shift-double click with the Select button on the icon of an open directory in the Filer, and it closes that directory and all subdirs etc. Use the Adjust button instead and it closes the window you clicked in too.

Ctrl-Alt click on the close icon of any window and it'll close all windows (Tip: do not do this to check your memory whilst actually composing this post in a NS window!).

Ctrl-Alt click on the iconise button of any window will similarly cause all windows to be iconised.

On November news in brief:

Yes, that's not a feature of Aemulor, rather of the Iyonix. You really need to set it to draw to a buffer; it does have a dramatic effect upon the speed and playability. Aemulor doesn't support sound (it's technically tricky and didn't get included until later), so you need Aemulor Pro for the full experience. There's no appreciable difference in speed between the two versions, though.
