List of Mario Super Sluggers glitches
From the Super Mario Wiki
This is a list of glitches in the game Mario Super Sluggers.
NOTE: Unless otherwise noted, all names are conjectural.
Batting Eye Glitch
Eye Texture Glitch
Yoshi Train Home-Run
In Yoshi Park, if the player is batting and hits the ball into one of the Yoshi Train's passenger cars, the ball will disappear and the "Home-Run" message will be displayed. However, this glitch doesn't always work.
Occasionally, when Funky Kong or a Kritter charge up when batting, their mouth will be closed (Funky Kong) or opened (Kritters). Also, when Donkey Kong uses the Barrel Swing, he will show a neutral expression on his face, but if it is seen during a replay, he will show an angry expression instead.
Wrong Voice Clips
In Toy Field, when the first player pairs with the third player, while the second player pairs with the fourth player, a sound glitch occurs when one team wins the match. The game assumes the first and second player pairs with each other (as with the third player and fourth player) and therefore, even if the third player wins the match with the first player, the third player uses the losing sound clip while the second player uses the winning sound clip. This can also happen vice-versa.
