In order to get (Arc)Elite to run on VA5000(Demo) you need to copy the dowloaded !SparkFS archive (b5052410.arc) to the 'HardDisc4' directory inside the 'VirtualA5000 Demo' directory in Windows. These should be:
C:\Program Files\VirtualAcorn\VirtualA5000 Demo\HardDisc4\
Once copied to this location (if thats where you installed VA5000 Demo), you should, on running VA5000, see that the b5052410.arc archive now resides in the URL of HardDisc4 (Just single click the HardDisc4 icon on the RISC OS icon bar).
Double click the archive, and you now should be able to see the !Elite files and run the game. At this point you can either run the game from here or copy the files into another directory to save running !ArcFS.
Don't forget to enter the task/command line (pressing F12 when the RISCOS desktop is displayed) and enter *Cache off. Press return/enter to return to the RISC OS desktop. Now double click either Gisburne or Jameson. An Elite icon should appear on your icon bar, from where you'll be able to launch the game - fingers crossed ! Select yes when asked if you're using a high-res monitor.
As for running RISC OS software/disk images (.adf files) from dos floppies, you need to load !Configure from the Apps icon on your icon bar. Go to Floppies, and click on the 'up' arrow/triangle to increase the number of floppy disk drives present. With one added, click ok. Now restart VA5000, and you should see a floppy added to you icon bar (with me so far ?!?!)
Now, with VA5000 in a Windows window (Alt-Enter from full screen). You will see a little floppy drive icon/button in the top left hand corner. Click on that and it should show you the contents of the floppy that you're wanting to access. Alternatively browse your disk till you find the file. Select it, and then click on Open. Return to your RISC OS desktop, and click on the Floppy drive icon. This should automatically display the contents of the RISC OS floppy disk image that you've been trying to open and allow you to run the program natively. Phew !!
Try that. Should work
