Just in case anyone might find this useful, I've been doing a fair bit of
tweaking/testing various stuff using different video setups lately, so to
make it easier:

I've updated my DBT.COM (DosBoxTweak) to include a monochrome option, better
resolution tweaks and added a few other things (it was basically a complete
rewrite). I've also added the ability to make it work in other editions of
DosBox besides my own.

I thought I had published this before, but could find no reference to it in
my site files, so I've added it to: DOWNLOADS/DBUTILS.ZIP

22Restarts DosBox with specified config "tweaks".      These override settings
23in DOSBOX.INI (which should have your preferred setup) for one session only!
24
25
26-?F: The default DBT filenames are set up for my edition of DosBox which uses
27 the 8.3 friendly name "DOSBOX.INI" instead of "dosbox.conf"
28
29I also mount Y: as the DosBox home directory, and assume that DosBox is
30launched from within that directory.
31
32    IF=Y:\DOSBOX.INI
33    TF=Y:\$DBT$.TMP             If BF= is NOT set, it assumes name only
34    BF=$DBT$.TMP             <- from TF= (after last '\')
35
36If your setup does not match this, use these options to set the correct names.
37
38Note: DBT reads Z:\AUTOEXEC.BAT looking for lines with: rem -DBT- ...
39 to preset options!     eg: rem -DBT- IF=dosbox~1.con TF=C:\$DBT$.TMP
40
41for help on name entry, see: -?S

43
44-?S: Command argument strincs have "escape" codes:   ~c
45
46    ~_=' '      ~(='<'   ~)='>'     ~!='|'
47    ~{anything else} = '{anything else}'        <- use for '~'

Feedback welcome, if you'd like to see something else added, let me know!
