Since this is a new forum on a website that has been reborn from ashes, like a Pheonix, I thought that this should be posted.. I realize that most people here know this, but for the people who have just discovered this game and stumbled here, then here it is:

Baldur's Gate: Dark Alliance
Level Warp & Invincibilty

PS2:At any time during gameplay, hold L1 + R2 + Left + Triangle and press START. After entering the code correctly, a special menu will appear.

Xbox: 1) Left anolog trigger down all the way
2) Right anolog trigger down a LITTLE bit
3) Y button
4) A button
5) Move left anolog stick to the right
6) Hold all that down and press start.

Game Cube: Simultaneously hold L, R, Y, Left on the D-Pad and press start.
Other GC Codes: 190,000 experience, 500 skill points, and all or most spells/feats.
Simultaneously press and hold L, R, X and Right on the D-Pad
: Cheat Menu
Hold X + L + R (half-way) + Left, then press Z
: Play as Drizzt
At the character choice screen, press and hold L and R, then tap A. Keep pressing L and R until Drizzt comes onto the screen.

Unlocks: Be Able To Use Drizzt Do'Undren: In A New Game Beat extreme difficulty.

Unlock Gauntlet Mode and Extreme Difficulty Beat the game on any difficulty level to unlock the Gauntlet Mode. After defeating Gauntlet Mode you will open up the extreme difficulty level.

Loading Screen Trick
While the game is loading and you see the text Loading, use the R3 anolog stick to move the flames left, right or up.

Carrying Capacity Glitch
Get 1 or 2 rings of strength and equip them. Pickup as much items as it will allow you. Now unequip them and switch them to any other ring you so desire. This will allow you to carry more than you are supposed to, but the only downside is that you don't want to drop anything or you can't pick it backup. Unless you equip the rings of strength again, and while doing this glitch you can't pickup anymore items.

Infinite Experience (without using Cheat Menu)
Similar to the Cheat ''Infinite Gold or Duplicate Items''

Get to a save point right before a boss that gives A LOT of experience. Example: Beholder, Drow Elf Sorceress, Dragon, Onyx Golem. Save the game.

Defeat the boss, then go back and save the game under a new file. Load the original file (before you fought the boss). Import the character from the new file (after you fought the boss). Go fight the boss again for more experience.

Repeat till you reach whatever level you wish. The massive experience you get should make it easy.

Infinite Gold or Duplicate Items
Have 2 players going at the same time. Being in town is a must. Then have one character drop all their stuff. Import the character that just dropped their stuff and they will have all the things that they just dropped but, its also on the ground. Pick up the stuff sell the duplicates and save. You now have more money. Buy expensive items with your extra gold and repeat this cheat again. The more times you dup the more gold you get each time.

Level 20 Character and 75000 gold
When in play mode, press L1, R2, Triangle, Left D-Pad, R3 and start simultaneously to instantly make your character 20th level, with 75000 gold, 1000 Health and 1000 Mana, and a minimum of 1 in every feat, including OTHER character specific feats.

However, downside is that your character does NOT gain any further experience points while playing, and is stuck at 20th level, with low level feats. The normal character max is 40th level.
