I know this has been done already but to make it more clear so people want have to click various links here is the information
Saturn
General:
- the bigger sprites affects things slightly. In Saturn Mode, the screen is slightly smaller which equates to a less room to manoeuvre. For example, on the Saturn, from anywhere on the screen Dhalsim can use his far standing fierce, and if Blanka is grounded he must block it, as he is unable to walk out of its reach. The screen mode can be changed to Arcade Mode, but this is still different to the CPS2 game.
-some slow-down during VCs; more noticeable when the larger characters are on screen. The slow-down also causes some inputs to not register in the same way as the arcade during a VC activation; Rose’s crouching Strong-> Short Spiral is harder to do, not impossible.
-
less meter gained for whiffing throws
-
“Inflation” during VCs removed
-
post air recovery invincibility if neutral state is avoided removed
Akuma-
Super air Hadouken can be blocked in the air

- new X-ISM crouching Short
Cody -
- air Hadouken freezing bug removed
Zangief

PS1
General:
-Super flash now rendered with proper 3D polygons
- different hit and block sparks
- gradient colour effect on vitality gauges; damage inflicted is always displayed as red
- lots of animation cuts
- Significantly reduced invincibility of VCs at start-up
- different VC2 and VC3 shadow timing to both the arcade and DC versions
- post air recovery invincibility if neutral state is avoided removed
Ryu:
- can cancel far standing Fierce and the second hit of his close standing Roundhouse in X-ISM
Birdie:
- standing Forward can no longer be blocked in the air
- air throw now throws them in the direction held - as opposed to the arcade game where he would always throw them forwards
Ken:
- larger throw range (?)
Dhalsim:
- limb speed severely reduced
- is able to cancel his far standing Short, Strong, Forward and Roundhouse into special moves in the Japanese version.
- new animation for X-ISM close crouching Short
Cammy:
- during a VC, a whiffed Cannon Spike can be cancelled into a Cannon Strike at its peak
- close standing Fierce-> crouching Forward no longer links as a 2-hit combo (?)
- far standing Strong-> standing Jab no longer links (?)
Cody:
- his taunt has mid-level invincibility, and can be used to avoid projectiles. V-Cody only (?)
- standing Short has less reach, so crouching Jab x 2-> standing Short-> Forward Ruffian kick is not possible as a 4-hit combo
Guy:
-Bushin Izuna Drop can grab cornered opponents
Rose:
Level 3 Aura Soul Spark can be rolled away from before the damaging throw part can connect. May also be true of the Level 2 version.

- hit box when jumping drastically reduced in size
- Glitch Driver removed
**
Dreamcast **(first version):

- Post air recovery invincibility if neutral state is avoided removed
Cammy:
- during a VC, a whiffed Cannon Spike can be cancelled into a Cannon Strike at its peak

Cody:
Akuma’s air fireball freezing bug removed.
Jab Criminal Upper behaves differently, so his corner trap/pressure game is greatly weakened

Commands after her 360+K during a VC are now performed in the direction Karin faces after the move - as opposed to the direction she was facing before the move, like the arcade version.
**Dreamcast **(second version):
Same as the first version but now crouch cancelling and crouch cancel-walk have been removed.
