Yup, so I typed it up more cleanly; here it is:
OK first off, port value is based on the number given to each player when they chose their character using that controller port; thus, port 4 is the highest port and port 1 is the lowest port. Similarly, in terms of port value 4 > 3 > 2 > 1 (like you would expect). Port priority is used to determine the outcome of ties and random events which inevitably take place during gameplay. Sometimes the higher port will take priority over the lower port and sometimes the lower port will take priority over the higher port, all depending on the situation.
Situations involving port priority and the various outcomes
- Both players grab each other at the same time. In this case the lower port will grab the higher port player.
- Bowsercide in a normal match (both players die at the same time). Here, if Bowser is the lower port he wins, if not, you go to sudden death.
- If you Bowserside in sudden death, you go to a second sudden death. If you Bowsercide again in that match, Bowser wins regardless of port.
- Kirby/Dedede inhale suicides have no advantage based on port in a normal match, and thus will result in a sudden death if both player are on their last stock.
- If this happens in sudden death, the victim of the inhale loses regardless of port.
- Wario bite suicide in any match will result in a stock loss for the Wario player before the stock loss for their opponent. The same applies for Donkey Kong's cargo throw suicide.
- FAS (Faux Super Armor) occurs when a player is grabbing another player and status effect of any kind (this includes explosives) hits both of them. If the player who is in a grab (grabbing or being grabbed has no difference) has a higher player slot (P4) then he will take the damage regularly but not be affected by knock back.
- If two characters transform at the same time, the character with the lower player slot (P1) will transform first.
For teams, the following combinations will result in the following advantages for each team
Key
Grab Priority advantage - if two players grab simultaneously, lower port wins.
Transform advantage - if two players transform at the same time, lower port transforms first.
Suicide advantage - one player remains from each team with one stock. If the player with the lower port suicides his opponent, his team wins (may be different for Gannondorf)
FSA advantage – Faux Super Armor (see number 5 above).
