racket, just keep calling me Cloud. Actually EVERYONE, keep calling me Cloud.
To change between 2.0 and 2.1 you press the R button in the options screen and the top option on the second screen is selecting between 2.0 and 2.1.
There were many changes from 2.0 to 2.1:
Version 2.0:
Unblocked PK combo causes characters to fall.
No pauses when running backwards
Player and CPU-controlled Shun and Lion automatically track when Shun or Lion scoot around behind the opponent
2P Lau floats higher when kicked, and is slower getting up
Version 2.1
Unblocked PK combo causes characters to stagger
Pauses when running backwards
Player and CPU-controlled Shun and Lion do not automatically track when Shun or Lion scoot around behind the opponent
Both 1P and 2P Lau react exactly the same to kicks and getting up
Kage's Koenraku-thrown fighters don't float as long, making it harder to get off attacks before they land
Jacky's recover from his Flip Kick is longer by 1/5 of a second, making him more vulnerable
If hit during a backdash, the fighter staggers
Height of Kage's Koenraku adjusted
Recovery from staggering after elbow, sidekick attacks now easier to do
In the case of an attack which involves falling to the ground, a down attack can hit, even if the fighter is not completely down on the ground
The stopping distance after a long-distance run changed from 3.0 meters to 1.5 meters
