fxspan.c is obsolete (and should be removed).
I recently rewrote the fxDDReadRGBASpan() and fxDDReadRGBAPixels()
functions. Before, these functions were returning bad (imprecise)
values. Instead of doing bit masking and shifts a lookup table is
now used.
The initialization of the lookup tables is dependant on the
type of 3Dfx card you have.
What kind of card do you have? Can you step through the
setup code (see fxInitPixelTables()) and locate the problem?
