As most of you know by now, there’s a method of making green units hostile to players and enemies (skips the allegiance check). This is done by editing a byte on the ROM, but what I’m trying to do is make the green units only hostile for a specific chapter.
Technically I can do this by using the VBA to memory hack the byte from RAM during that chapter. But obviously that’s not a permanent solution. So what I’m asking is: How do I get a third faction working for a specific chapter? I know Bloodlines does this (albeit in a different manner) so I know it must be possible.
