Get a later version of emTeX.
This line now reads:

% modes.mfj
%
def lj=[mode=hplaser[300]; output=pk[c:\newfonts\pixel.lj\%rdpi]; tfmlog];
def tfmlog=[output=tfm[c:\newfonts\tfm] log[c:\newfonts\log];];

The dvidrv family substitute the $r or $s with the desired size.

It depends whether it is an environment variable (in which case a $
is used because % is used by DOS) or whether it is in the modes.mfj
file (in which case a % is used).

For your version of mfjob the answer is Yes.
For the new modes.mfj, make up your own maketfm.mfj file, and the tfm
file will be put in c:\newfonts\tfm.

Yes. I have done this.
Remember that they are binary files.

Why not use cmr12 magstep half?
If you really want cmr13.tfm, there are some files on ymir.claremont.edu
for making odd sized fonts.  I can't remember the exact location.
