SUPPRESS Version 1.06 12/27/86
Suppress was written in a fit of pique. Why does every game insist
that I have a color screen simply because I have a CGA card? I have a
CGA card and a GREEN screen not a $600 color monitor. The game
instructions are printed in multiple colors which appear unreadable.
The game itself is unplayable. Then along came SUPPRESS, SUPPRESS is a
video preprocessor. It traps all screen writes at the BIOS level and
SUPPRESSes the color. It does it by inserting itself at BIOS INT 10h
and preprocessing the call to INT 10h before calling BIOS. Obviously,
the games that write directly to the video buffer will not show any
improvement. However, any game using DOS or BIOS calls for screen I/O
should greatly improve.
When should you use SUPPRESS ?
Whenever a program thinks your GREEN screen is a color monitor. If
a program displays hard to read output due to similar shading of the
background and the characters, try SUPPRESS.
How does SUPPRESS work ?
SUPPRESS is a terminate and stay resident ( TSR ) program. You run
SUPPRESS once and it is ready until you reboot. SUPPRESS takes over
INT 10h ( BIOS Video call ). It looks at the request being made BEFORE
BIOS sees it. It then decides what, if any, preprocessing needs to be
done to ensure legable output. To remove SUPPRESS you MUST reboot.
TRY IT, IT CAN'T HURT !
