I don't have that setting, where that setting is on the screenshot I have "Emulate Disc Speed"

Had two runs rejected for fast loads a little while back, and I decided to go test it and it seems my loads are about two seconds faster than they should be? I've looked at the properties in dolphin, but I'm unsure of what settings there should be since the guide in the rules section on src is from an older version of dolphin. If someone could help with this I'd very much appreciate it
