Rule Settings

Rule: KO (5, 10, 15, 30, 99); Time (2, 3, 5, 10 minutes); or Survival (3, 5, 10, 15, 30 lives) [set how the battle will be decided]

Interval: 5, 10, 20, 30 seconds [the amount of time you have to set your Ground, Air, Defense settings when knocked out of battle]
Auto Handicap: On/Off [supposedly allows you to power up the 1-hit KO bar when nearly defeated--personally, this hasn't had any noticeable effect on a fight]
Computer: Extremely Weak, Weak, Average, Powerful, Super Powerful [set how well the computer fights for the character(s) it controls]
Location Settings
Press the L-button to change the settings here.

You can set the order of the settings to use for the fights. You can set it so that the fighting will take place anywhere from eleven different sites. If you do not, the computer will select a place at random. The choices are Emerald Beach, Tails' Lab, Chao Ruins, Battle Highway, Club Rouge, Amy's Room, Library, Metal Depot, Holy Summit, Colosseum, and Green Hill.
  

Info
This mode pits the character you choose against other characters in the game. To win, you must be the first character to cause 10 KOs in each round. You lose if another character causes 10 KOs before you do. The character(s) you fight will change by round. There are three levels of fights signified by 1 (easiest), 2, and 3 (hardest) rings. The fights are the same for all three levels.
Scoring
Time: If you win the round in under 3 minutes, you will earn points. The faster you are, the more points you earn.
Special Attack KO: 1000 each
Down Count: Start off with 10000; you lose 1000 each time you are KOed
Offensive Hit Percentage: Based on the amount of attacks that land; 100% = 10000 points; 90% = 9000 points; etc.
Bonuses: In addition to the points you earned above, you get an extra 10000 points each if any of the following occurs--1) fight lasts less than 1 minute, 2) all your KOs are by special attacks, 3) none of your KOs are by special attacks, 4) you are never KOed, 5) 100% of your attacks land, 6) you never take damage, and/or 7) you are the only one to cause a KO.
