I want the technic please because i don't know that and it's usefull.
After some game they are missing for me: the sound of units (i can change it by editing the Contra008.ctr) and the voice of unit by editing the Contra008VOrig.ctr
One question, after editing a file, do i have to keep the "French" folder (who contain all of file extract from Contra008.big) or I can return the Contra008.big to .ctr and only use the Contra launcher ?
Thanks for the help.
