Bit -> what it does
0 -> double battle bit
1 -> crashes, so I dunno
2 -> normal wild battle one. seems to say not to load the randomize pokemon method, as when called combined with the next flags produces ???????s
3 -> trainer battle flag
4 -> dims the screen (prof oak battle). If no string is present to print, crashes
5 -> seen nothing special yet.
6 -> puts you to the left, and deletes your first pokemon. Meant to be used with the double battle bit, as a double battle with two different trainers. Not even developed enough to work properly.
7 -> Starts safari encounter. If you try double battle, you mess up the whole battle.
