The beebfile directory is (if I remember correctly) the directory
under which you are current directory when you run it - from the
ReadMe.1st that comes with the source:

  Now you have to get three disc images from a beeb.  One of an 8271 dfs
  (I used DNFS).  Place that in beebfile/dnfs (even if its a dfs). 
  Put the basic rom in beebfile/basic and the OS in beebfile/os12.  These
  images are just 16KB binary files.

No.

Certainly the way I left it a long time ago it would only work on 8-bit;
I use the palette on the X display to emulate the flashing colours and
the like; 8 bpp cards were the norm when I wrote it and it would
have slowed the poor P90 I wrote it on down even more to do the full
emulation in 24bpp that I did in the later ArcEm.
