A "bug" was recently brought up in Pokemon Showdown:
My reply:
So I misremembered how the DS handles Gen V battles, but the point remains valid: there is no reason why we should be playing by Nintendo's rules for 6v6 Singles battles. We already enforce sleep clause and evasion clause and form our own banlists. Why should we go by Nintendo's rule of what constitutes a victory?
This is definitely not a trivial issue: not only does it affect our simulators and their ladders, but I would imagine this would be an issue as well for non-VGC Wi-Fi tournaments.
So what is the Smogon policy on what constitutes a victory and what constitutes a tie? Should we be aiming for 100% accuracy with our simulators, or can we use our better judgement?
My personal feeling is that we should play by "PBR" rules: a battle ends in a tie if neither player has any remaining pokemon at the end of the battle, UNLESS one player has used a move such as Explosion or Destiny Bond to achieve this effect ("Self-KO" clause).
Again, you can tie. As far as I know, you can't tie at all ingame. There are certain conditions that dictate who wins in various "both die" scenarios.
My reply:
I would view this as a feature, not a bug. Wi-Fi room battles will mark these kinds of things as "draws" (Wi-Fi room battles actually have a very generous definition of draw--e.g. no self-KO clause).
I don't have a recording for the DS, but this is definitely the case for PBR.
The bottom line is that there are no Nintendo-set rules for single 6v6 single battles, so we get to decide them for ourselves.
No, you are incorrect, from what I know.
In generation 5 (not generation 4 to which you linked me; I'm well aware you can tie in gen 4) I'm fairly sure you can't tie. For example, 2 mons dying to LO recoil / attack simultaneously will result in a win for the LO attacker (in the battle you linked me to, had it occurred in gen 5, the staryu player would win). Perish Song results in the death of the faster mon, etc.
(sidenote, that video seems familiar; might have seen it in my PBR days!)
About the tie...
I have done some forced battles to tie. First with perish song, the singer and the slower pokemon won. Then, with life orb damage, the attacker won although it die too by the damage. Finally, I achieved a draw, both trainers pressed "run".
PD: my english level is low. Sorry.
DS Battles:
60-53940-33112 Perish Song.
52-66455-51927 LO Attacker.
69-36126-53320 Run both trainers.
