A very simple MML script which helps me greatly with some of the in-game flashes which are too bright. Feel free to edit to suit your needs.
Made this for Scraniel, but might help others. Just makes some of the flashes less bright. It should be copied into the Scripts directory of Aleph One, and as of AO v1.6, does not need to be enabled in preferences. It should work with most 3rd-party scenarios, depending on what those creators have modified.
