Sorry I wasn't able to answer you're last questions very quickly, but you're completely correct in that the information passed to the hardware needs to be the difference from the previous position. This is because a real mouse has no idea where it is compared to a fixed point, only an idea of how far it's moved in a certain time. > Keyboard support is working. > HostFS and Extension ROMs compiled in and work ok.

Yes, it's a bug in path translation, well more of a 'not written yet' rather than a bug :) (the dots and slashes are used as directory seperators in RISC OS and Posix). > SnoopDOS is not reporting that ArcEm is even attempting to read the > file, and nothing appears in ArcEm's output either, yet RISC OS gives > an error message.

Another chance for an improvement. Possibly something along the lines of DispKbd_HostFinalise() that is called to tidy up all the host specific parts. > If anybody wants to check out the archive or add a link to the ArcEm > website, it will shortly be available from: > http://www.os4depot.net/index.php?function=showfile&file=emulation/computer/arcem.lha > I'll add this to the website in progress (which has got a bit further, dummy screenshots page, and I'm about halfway through updating the manual). > NB: The source code is not included, I thought it would make more > sense to commit it to CVS.

Basically you need a Sourceforge username, and for Ralph or Peter N to add you to the list of developers that can commit changes to ArcEm. Can you let me know if you've used CVS before, as that would help me give you the right level of info. > I promise to be a bit quieter from now on :) Hah!
