names must conform to the following convention:
ImageFil.000
ImageFil.001
ImageFil.nnn

files .000 to .nnn.
Image Control Switches
Miscellaneous Switches
Animate n frames. Files ImageFil.000 to ImageFil.n-1 are displayed in sequence to cre-
ate an animation effect.
The sprite is displayed in three color mode with the fourth color transparent. This is just
one of the color schemes available to the sprites.
The 8109 sprite load method is used. The sprite image is loaded into the display ’slot’ by
first setting the VGA registers to Planar Addressing Mode rather than using Sprite Write
Mode.
/Sxy can be specified as /Sx, /Sy, or /Sxy to stretch the sprite in the x, y, or both axes.
Vertical expansion disable. On LCD displays where vertical expansion is enabled, sprite
movement may look jerky and uneven. Disabling vertical expansion corrects this prob-
lem.
Display the help screen.
Quiet mode causes SPRITEST to load without displaying either the copyright notice or
errors. This option is useful for demonstrations where multiple images are loaded.
Uninstall SPRITEST. Attempts to remove the TSR portion of Spritest from memory.
