giants 1.4 no-cd here
 

darn interplay...thier new patch reintroduced a wierd bug
it cant find the cd i bought w/ the money i earned cutting lawns for the last 4 years.

open giants.exe in a hex-mode capable editor.
at offset EE8C6, change the "75" you find to an "EB".
do the same for offset EE8F4.
save, run and enjoy.
