* Using master balls to catch Pokemon. This makes the game too easy and takes away the challenge of catching Pokemon.
* Using cheats to get items. This can give players an unfair advantage over other players.
* Using cheats to change the game's difficulty. This can make the game too easy or too difficult, depending on the player's preference.
* Using cheats to change the game's graphics or sound. This can make the game look or sound different, which can be distracting or unpleasant for players.
It is important to note that using cheats can corrupt save files or even damage the game console. It is always best to play Pokemon Platinum without cheats in order to get the most out of the game.
