PSP
For the first time in the SmackDown! series, this game is also available on the PlayStation Portable. Although it is very similar to the PS2 version, there are special features that are exclusive to this version that the PS2 version did not bear. Because of this, to unlock the full features of each game, USB connectivity between the PS2 and PSP is needed.
Jake "The Snake" Roberts is the exclusive PSP Legend and can only be played in the PS2 version by connecting the PSP to the PS2. However, before the PSP game was released, cheat devices also allowed Roberts to be unlocked. Other notable differences between the PS2 and PSP versions include the lack of in-ring commentary and the inclusion of voiceovers from the more popular superstars. The only major problem seen by most gamers was the game's horrendous loading times. They were so long that there was a warning about the load times when a created superstar is chosen for a match.
The PSP version includes some features that were not included in the PS2 version. These features include three exclusive minigames that are playable from the start. All of these minigames offer single player and multiplayer modes. In multiplayer mode, players can make use of PSP's Wi-Fi functionality. Each mode allows up to four players to join in and play over a local connection.
The first minigame, WWE Game Show, tests the knowledge of wrestling fans by offering 500 multi-layered wrestling questions. The WWE Game Show covers every wrestling topic imaginable including costumes, trends, music, finishers, styles, history, feuds, and more. Most questions include excerpts of songs and have players guess the tune or players are shown a video clip and must guess the match the clip is from. The questions range from easy to extremely difficult. Other minigames include a poker game and Eugene's airplane game in which the player navigates Eugene around the ring in the fastest time.
