Sorry for post in this old topic, but my question is not worth of new one.
I already tried this, but even if i edit bullet.png/.bmp the trail is still nearly same. Grenade trail is still somewhat green. M79 works only when u use dark colors.
Is this possible to edit or not?
EDIT: YES the trail is black but i want red trail so it looks like i need: green + (bulletcolor) = red
