Yeah, if you are using a clean Fire Red ROM, go ahead and put it around 0x0800000
Once you got that covered, just put in a script...
callasm 0x800000
(If you inserted it at 0x800000)
WIN, though I can't remember if you are supposed to use 0x800001... if 0x800000 doesn't work, try;
callasm 0x800001
EVEN if you inserted it at 0x800000, try 0x800001 if it doesn't work... (Don't re-insert it though, lol)
