- Holding start on Rock's portrait in the Stage Select screen will endlessly play the "error" sound.
- If you hold Down and press Jump repeatedly, Rock will throw out dust clouds like crazy. However, this will not make Rock slide forever.
- The Neo Rock Buster charge shot does about 6 damage to most minor enemies rather than 3. (Intentional?)
- Large Energy Capsules restore about 8 energy. They should restore 10.
- As Splash said, E-Tanks do not respawn after you continue. (Intentional?)
- Rock does not teleport in from the top of the screen if you continue from a checkpoint.
- Projectiles reflected from Ryu (using Urien's weapon) can sometimes fly backwards, under the right conditions. (They work just the same, though.)
- Dhalsim will sometimes face the wrong way while using his Super Move.
- Blanka and C. Viper will, on rare occasion, forget where they are in their boss rooms and "cling" to a corner until Rock moves away from said corner. This is especially strange for C. Viper, as she does it during her Super Move.
- It is impossible to get a "Perfect" on a boss if you have less than 32 units of health, even if the boss never hits you. (Intentional?)
- If you die in the Boss Rush stage, the background of the teleporter room resets to normal. (It's supposed to change after five bosses.) After you beat another boss, though, it changes to the second background again.
- On rare occasion, the game won't pause while recovering energy. (This only happened to me during the Boss Rush stage, however.)
Cannot slide through boss doors.
Pausing loses charge.
Cannot fire small shots while charge shot is on screen.
