Monkey Head Crowd	PS2 NTSC version: O→B→Y→Y→O→B→Y→Y PS2 PAL version: Y→Y→B→O→Y→Y→B→O X360 version: O→Y→B→B→Y→O→B→B The crowd will have ape heads.
Performance Mode	PS2 NTSC version: Y→Y→B→Y→Y→O→Y→Y PS2 PAL version: Y→Y→O→Y→Y→B→Y→Y X360 version: B→B→Y→B→B→O→B→B Makes the highway and heads-up displays (HUDs) invisible, revealing only the stage. This cheat makes the game harder to play, in which you will have to guess notes at the right time by memory and you can't see how well you're performing.
Unlock All (PS2)	NTSC version: B→Y→O→R→O→Y→R→Y→R→Y→R→Y→R→Y PAL version: B→Y→O→R→O→Y→B→Y→B→Y→B→Y→B→Y→B→Y Unlocks all characters, items, and Quickplay songs in the game. This cheat disables game save. IMPORTANT NOTES: (Auto) Game Save feature must not be pre-disabled. Specifically, when game DVD is booted the system checks for the presence of PS2 memory card; if none found the option is given: Continue play without game save? Yes/No. If “Yes” a second option is given: Disable auto-save? Yes/No. If you choose “Yes” (which you would normally do if playing without a memory card because after each completed song the game hangs up while trying to auto-save the performance stats to an empty port) the cheat code above (and only the above cheat) will not work. If planning on using this cheat; choose “No” then continue to the Main menu (the one where you choose: Career Mode, Quick Play, Options, etc.), tap in the code. Once the code is accepted; confirmation in white lettering appears stating that the Unlock cheat is active and that game save feature is disabled. After message disappears, you are able to play any song you want in either Career Mode or Quick Play mode, however, you can only play the songs normally available within the particular mode; which means that more songs are available in Career Mode. Also, you can directly choose to play any/all songs in Easy difficulty the first time around, which may not normally possible to do on certain songs until you have invested a lot of time into the game. It seems that especially in the case of encore songs you must first play them in at least the Medium skill level because the song which precedes it doesn’t seem to initiate an encore song at all unless it is played at the medium skill level or above. It may not be possible to change skill levels between an encore song and the associated song.
Unlock All Songs (Xbox 360)	NTSC version: B→Y→O→R→Y→O→B→Y→B→Y→B→Y→B→Y→B→Y PAL version: B→Y→O→R→Y→O→B→Y→B→Y→B→Y→B→Y→B→Y Unlocks all Quickplay songs in the game. This cheat disables game save.
