Adding custom *#code# for 5e0ID

Hi, i have seen in some flashes that people have made their own custom *#xxxx# or #xxxx# and even *xxxx# codes to trigger 5e0ID's and i was wondering if anyone actually knew how to do this??? Tried searching, but the search engine doesnt find anthing starting with *# i think :(

You can only change existing *#xxxx#
The way they changed to *#xxxx#, #xxxx# or *xxxx# is pretty simple - edited by hexeditor in flash files :)
How to run function by entering that code - long story. You must study branch link in flash files :)
