Bug
#5: If all of your Pokémon faint while you're on the Cycling Road, you reappear at the last Pokémon Center you visited. If you try to get on your bike at that time, the message "You can't get off here!" appears. This also happens when you aren't riding your bike.
→Fixed.


#6: The Player's Pokémon has no PP, the opponent cannot use any moves, the player's [other?] Pokémon are all fainted, and the player has no items they can use. If the player has no means of fighting left, the player's turn cannot end.

#9: After grappling moves (like WRAP and BIND, etc) hit, the defending player gets a "It can't move!" message. The message for the first attack reads "Enemy ____'s attack continues..." This message continues to repeat with each attack (2-5 times). However, However, after Fire Spin hits, the game will not always notify the player that defending Pokémon is always unable to move. The message is contradicting what happens. The attack itself continues as normal.

I entered Agatha's Elite Four fight. I had a Pidgey with no PP except for Mirror Move, and Agatha's first Pokémon, Gengar, used Substitute. Pidgey used Mirror Move and also used Substitute. After that, Pidgey used all its PP, and could only use Struggle. Because of Gengar's Substitute, Pidgey couldn't damage Gengar. Because Pidgey's status was Normal, Gengar's moves couldn't hurt it. Because Gengar can't use Struggle and is a Ghost Pokémon that cannot be damaged by Struggle, I could do no damage whatsoever. Because Pidgey can't damage Gengar and Gengar can't use Struggle, no one can sustain damage. Because Agatha's other Pokémon are also Ghosts, and the player only can use Substitute, and can't use Ghost moves, Pidgey and Agatha's Pokémon cannot do damage. As a result, neither the player or Agatha can deal damage, and it becomes an endless loop. This happens with any Ghost-type Pokémon.

TM39, Swift, does not work in Yellow Version the same way as it does in Red and Blue Version. In Red and Blue Version, Swift has an accuracy of 100%, but in Yellow if the opponent is Flying or Digging, when you use the move, it won't hit. If you use Swift while in a Link Battle with Red or Blue, Red and Blue will say it will hit, but the Yellow Game Pack will say it missed. Therefore, the damage on the enemy Pokémon will be shown on on Red or Blue, but not on Yellow. This causes graphical glitches on the Pokémon and have effects on the Hall of Fame.

In a duel in the Colosseum, when Player 1 uses a recovery move and Player 2 uses Counter, Counter does not function properly. Normally, Counter does double the damage of a physical move that hits it. Instead, the move does the damage of the last move that hit it. Because Player 1's Pokémon was hit by Counter, they immediately send out a new Pokémon. Then Player 2 uses Counter again on the new Pokémon. Because Player 1's Pokémon doesn't attack, instead of taking the damage from the new Pokémon, takes it from the last attack. Player 1's new Pokémon is sent in and the process repeats.

In battle, I was facing Pokémon with Self-Destruct (TM36) or Explosion (TM47) and I used Substitute. When the enemy Pokémon uses Explosion or Self Destruct to break the Substitute, the enemy Pokémon's graphics disappear, but it hasn't really been defeated. The Substitute is destroyed, but the process of exploding and fainting is prevented. You can continue the battle, but the enemy needs to be defeated again and its graphics don't come back. This happens both in the Colosseum and vs NPCs and in RGB Mode.
