[M1] NES Editroid Q: Activating "Time Bomb Set"

[arseus543]

I dont know how active this forum will be but im in a bit of a pinch. Im making my own map of NES metroid and I wanted to make Tourian in a way that activates the time bomb (900 sec countdown) after killing a fake mother brain (I just made an unguarded MB basically). i noticed thought that after my escape route, the "Real" (Or One i actually put stuff around) MB is already gone (Obviously the game can only have and kill 1 MB).
Is there any way to activate the time bomb and then fight Mother brain (Preferably by killing one of two mother brains, but if that not possible ill take something else)? Thanks to anyone who can answer this ASAP (No true rush but was going to send to a friend in a day or two).

I think you're going to have to do some programming to make that happen.  If that's something you want to try to tackle you can try to catch Snarfblam on the IRC chat (see chat link on main site).  He might be able to answer some of your questions or at least set you in the right direction.
