i just ran a lot of tests, and thought it might be useful to you guys:
1- when ir used the walk thru walls code to get around the lady and out of amity, as usual, chimchar (i was using) disappeared. i kept walking and i went out into hearthome and went to the right of hearthome where there are trainers and wild pokemon (route ???) when i tried to fly or use my bike, the game still thought SOMEONE WAS WITH ME! it said you cant use that when someone is with you. so part 1, the game thinks that someone is still with you.
2- i went into the tall grass while the game thought this, and when i got into a wild pokemon battle, it showed ME anD ROARK FROM STARK MOUNTAIN (he was the last person i teamed up with). the wild pokemon came up as lvl 19 staravia and bidoof. i had chimchar in the battle, and roark threw out claydol. so for part 2, since i am in a battle, and the game thinks someone is with me, it probably used roark because probly when u first talk to roark, the game "activates" some sort of code to make the game think you are with roark. i guess when he leaves you, it deactivates a code in the game that someone is with you at all, but IF you are with someone, the last activated code was roark?
3- i went into a trainer battle while the game thought i was with someone, but since those trainers are single trainers, it didnt show roark in battle with me. it just went along like a normal battle....except for one thing...after the battle, ALL MY POKEMON WERE FULLY HEALED! just like when u have a partner...
4- i was walking on water (walk anywhere cheat) and a wild pokemon battle started while the game still thought i had someone with me...the wild pokemon were a psyduck lvl19, and a NOTHING pokemon, lvl 0... then my trainer threw out chimchar, and NOTHING lvl0 as his partner! chimchar could not aim his attack at either of the NOTHING pokemon, and i couldnt control the NOTHING pokemon either... they were there, but didnt do anything. once psyduck fainted, battle was over.
i hope this is something u guys can work with
