I submitted a patch to the ncrt/ocrt guy a bit ago... my *crt unit is now
heavily modifed and does not work as documented or I would send you it...
In ncrt.inc:
After the lines
{ load the color pairs array with color pair indices (0..63 }
For bg := 0 to 7 Do For fg := 0 to 7 do cp[bg,fg] := (bg*8)+fg;
Add:
{ Set color 0 to black on black (Also used for dark grey }
cp[COLOR_BLACK,COLOR_BLACK]:=7;
cp[COLOR_BLACK,COLOR_WHITE]:=0;
I think that was all that was required for the colour fixes.
