This has been released before but among all the SD methods being released and a bunch of people saying they don't work, this one is has been the most successful so far.
First, for all of you who don't know how to do the SD hack follow this thread.
After that. you should have a CT with 11 addresses.
I grouped it just for reference.
For the monster addresses that are red, i set the hotkey to "Ctrl+O"
For the monster addresses that are blue, i set the hotkey to "Ctrl+P"
when setting a hotkey have it set the value to 0
you can use your own hotkeys that you prefer.
Then when you enter a dungeon, use either the red or blue addresses to kill half the monsters. Wait a bit, preferably until the dead monsters disappear, then kill the rest of them. If you run your dungeons like this, SD won't be detected.
Note: Be sure to use the Perfect Hack but freeze it to 200 or 250, higher numbers are not neccessary. I usually hotkey it to Ctrl+P "increase value" by "100"
hope this helps
