RedEdit in the system 7 days was a godsend in my life. Hacking new sounds into Maelstrom. Changing character names in Pararena. Stumbling into learning what a sprite was.
And it was a staple of Escape Velocity plugin editing too. Very fun program for a child with an old mac at that time.
The ResEdit days! I changed every sound in Marathon to the point it was unplayable. I had no idea what I was doing but I was fascinated.
I don’t think it involved ResEdit but we once changed the Starcraft sounds at one computer in the school Mac lab so that when you made a dragoon it would play “carrier has arrived.” Freaked opponents out all the time.
