• Problem that prevents VirtualAcorn from starting normally.
• Error message displayed inside RISC OS.

Is RISC OS showing an error message saying that file 'ADFS::(something)' is Not Found?

VirtualAcorn products use the HostFS filesystem, not ADFS, IDEFS or SCSIFS.. If the error refers to a file that doesn't start with 'HostFS::(something) choose 'Yes'.
