I've seen glitch topics in both of the other game boards, but they often repeated or were hard to look through, so I decided to create a complete list. If you find any more, post them here and I can easily add them and will create a 'Golden Sun DS Glitches' part when it comes out. Please provide clear instructions for achieving the glitch and
Test it first! If you can't test it, tell us that it's untested and I'll test it if I can. If not, I'll just put an untested label by it until a kind someone does test it and either confirms or denies it (and posts their results here).
General glitch assistance:
Return to last sanctum trick: This is useful if you get stuck in an area where you cannot cast retreat (such as in SW Atteka Islet where you can gat stuck in a box). At the menu screen hold L+R+START as you press 'A' on your file and you should return to the last sanctum you visited.
Shift glitch* (the ctrl key of the golden sun games): Get either Felix or Issac to under 6 pp and set the L or R button to Retreat and go to a dungeon, try to use retreat with the L or R button and after it doesn't work, go through a door, you may trigger some glitches. This can also mess up the game in wierd ways if you try it in different places. Another way to mess stuff up is to use the glitch, but don't go anywhere in a dungon, save, and reload the game. You may end up in the outside of a map. Places this works (in GS: TLA) are such places as the lighthouses, towers, shaman village, madra catacombs, gondowen cliff cave, Great Gamboa statue, Yampi desert cave, Anaemos inner sanctum, ect.

Tornado transparency glitch: When you are at Crossbone Isle's overworld portion while the Tempest Lizard's pink tornado is present on the northwest beach, the tornado is ordinarily transparent, and remains so when you go into the Psynergy menu and then come back out. However, if you go to the Djinn, Item, or Status menus, it will lose its transparency to become fully "solid". It returns to its typical opaqueness once you enter Crossbone Isle and come back out to the world map area. Also, it apparently vanishes if you press the L or R button while Isaac is caught by it.
Glowing people: Once you obtain the Halt Gem, assign Halt to the L or R button and go to Xian and cast halt on any of the people training in the dojo (or to the guy with the weights in Imil). Then, save and restart the game, the person should still be glowing.
Migrating across the sea: If you stand at the tiny point of land farthest into the Karagol sea by Kelay Docks, you can encounter the enemies from the other side of the sea.
Play with only three characters glitch: use the shift glitch in the room where Mia joins your team, before she does join, then exit down the stairs. You end up in the lighthouse top where you can fight saturos and go on with only three characters. (note: this will allow you to get more then 7 djinni per person)...thanks go to lelouis for finding this glitch and posting photage of it on his youtube channel
Lamakan Desert Reveal Glitch: Go to the are where you fight the Maticore (the sand waterfall where you use reveal to find the large passage out of the desert) and use reveal, then the shift glitch before walking out of the reveal space. The entrance should still be there. Thank you MegaDarkNero for finding this glitch.
Golden Sun: the lost age :
Get back to gs1 land: Go to the beach directly southwest of loho (the mining town) and go to the southernmost point on it (in your ship) and face the edge of the mountain. Get out of your ship and you should be in GS1 lands, although everything has been removed.
Walk through the desert: in the first desert you go to (the one where you get Scoop) go to the very edge of the desert on the world map and cast Sand. then move into the desert and 'un-sand' yourself. You should be able to walk on the desert.
Garoh night to day+possible pillar glitch: Go to Garoh when it is still night there and go into the village, then go back to the path to it. On the first pillar you need to move, move it and then go EXACTLY half way between the pillar and the place where you slide down. then move the pillar back into place. you should be able to go down the mountain farther and then go back to the top...instead of changing from day to night as you go up, it should go back to day. At the final pillar before Garoh, the one you push down, push the back arrow as you are pushing it off and there should be a pillar glitch...I'm not sure.
Cow glitch: In N Osenia Islet, after giving the Red Handkerchief to the cow, but before leaving the map, save where the cow was standing, and when you start again Felix will be stuck inside the cow, unable to move. You have to use the 'Return to last sanctum' trick to get out of this.
Sw box glitch: At SW Atteka Islet, after pressing the box into the water where it would stay put because of an earth pillar in the water below it preventing it from getting carried away down by the water, saving right near the treasure chest, turning the game off, turning it back on, and reloading the save will cause the box to disappear, and you will be stuck until you reload the game while doing the Sanctum Trick. If you saved while on the box itself and reloaded the file, you will be standing on the water, and can now walk on water in a small area enclosed by invisible barriers. Use the 'Return to last sanctum' trick to get out of this.
Crack in the air: In mars lighthouse, after you beat the fire dragons, use the fireball launcher with the 'blaze' psynergy and a crack will appear in mid air.
Magma rock glitch: In the interior of magma rock, go to the room where you can fill/drain magma and get into where the magma usually is, go over to the area beneath the statue and cast burst towards the statue. The pool fills with lava and you can walk around in it. The glitch using burst on statues above you can be done anywhere on magma rock.
Make Prox brighter: when in Prox, cast reveal and then walk out of reveal's range. The town will be a little bit brighter.
Taopo wall glitch: Where you find the djinn 'flower' in the Taopo swamp caves, there are three slopes you can slide down on. If you slide down while holding B+down+right you should be outside of the wall.
Ankohl Ruins entrance glitch: In the Ankhol Ruins, when you slide down to the last part of the stone head and exit the room, the entrance to the next room will be as if you fell into in instead of going through the door.
Jumping over rocks in Shaman Village Cave: In Shaman Village Cave, the largest chamber contains several rock that can be jumped over if you are in a position to jump over them with the 'down' button.
Ship hovering glitch: if you have the wings for your ship and you cast 'Hover' while sailing, the animation for the ship flying will occur, but you cannot fly over anything but will not encounter monsters.
Mind reading in Mikasalla: If you have transferred data from GS in which Issac won Colosso, go to Mikasalla and there is a gladiator there. Mind read him before talking to him and his speech bubble should instead be a 'mind read' bubble.
Anemos sanctum glitches: (1) Go to the room with the bolder that you can lift, push the pillar under the bolder and where you are supposed to put it (at the far left side). Then, walk into it from the left and you should be inside of it for a moment before coming out on top of it. (and becoming stuck)
(2) In the small room joining the top door and door to the right of the larger room (with the lift puzzle, the one with the bolder). Walk to the top left point on the wall (around there) and you can walk upwards through it.
Shaman Village trial road item glitch: When first doing the trial road challenge (before you beat Moapa) drop items from your inventory using the 'drop' option in the menu and then go to the squares that allow you to forfit the competition. You will get now have the items, but also they will be available in stores. (doesn't work with rusty equipment or stat boosters ((Apples, Mints, etc)) )
Shaman Village trial road hover glitch: After beating Moapa and obtaining the hover jade, go back to the top of trial road to the Hover area and go towards the wall, you will get stuck.
Air's Rock climb on the wall: This actually works in several places but while climbing horizontally, continue moving as far as possible before climbing vertically. If there is a ledge beside you you should appear to be on top of it...it only works on some places though...
Play as only Felix for a short time: Start a new game and go to Idejima. Use the Return to last Sanctum trick. You'll appear in Dalia's Sanctum with no party members with you. after using this glitch, you can only leave Daila the way you came (back towards Idejima) The moment after leaving Daila, the Echo djinni would join your party, at which point Jenna and Sheba would appear in the party.
Walk and talk glitch: Go to the dead serpent. Go to the left side of him. Walk as far to the left as possible. Walk right and once you collide with him, press 'A'. Your character should be in the walking animation. This also works on the right side of the serpent.
Vanishing shadow glitch: Go to any room with the statues that shoot fire in Mars lighthouse. (The closest one is the door second from the left than into the larger door.) If the statue is able to shoot you off the ledge, your shadow will disappear when you hit the ground. This works at all the statues in that mentioned room, except for the one on the very far right.
Push glitch in Treasure Isle cave: Below the room In Treasure Isle cave with the Lift/rope puzzle there is the big room. At the top there is a pillar that blocks your way but you can face it and move it towards you, but you can't push it back, you have to use move on it. (found by The Abominator and tested by Syve)
Aqua Rock glitch: When sliding down the waterfall coming directly down out of the lake you use to get inside aqua rock, run diagonaly upwards and towards the right side until you fall, then immediately let go of the directional buttons. You will fall off of the screen, but if you try to go left or right, you'll exit the area.
Northern reaches glitch-on the world map between the Northern reaches and Prox, go just north of the entrance to the reaches and keep facing the small sliver of land beside the river and pressing A. You should eventually get out of the boat and can travel into the northern reaches (where you should only be with your ship) and can walk on the water and the ice. (found by Power Plus 5)
Lamurina scoop glitch- Stand on the right side of the topmost right statue before the lucky metal spring and face right. Cast scoop on the patch of flowers with the butterfly and the animation is the one that suggests that you found something, but nothing is there.
Battle room barrel glitch- In the lobby for the 'battle' option at the main menu, go the the far left, below the barrel just below the arabic-looking guy and press down to walk against the wall, then go up and the barrel will be 'over' you.
Get to Dullahan quickly: Inside the room you get the Charon summon, use the shift glitch and leave either direction. You will end up right where Dullahan is.
Glitched Kraden and Witch doctor guy: Use the shift glitch in the Great Gamboa Statue, then, before leaving the area, save and reload your game. You should end up in Gamboa's mouth with Images of Kraden and the Witch Doctor somewhere in there. (Use escape, not shift glitch, to exit)
Magma Rock game freeze glitch: in Magma Rock, using Burst on the right small statue (the last ones in the inner Magma Rock) in a certain distance will make Burst "burst" the air. And then the game freezes for about 15~20 seconds.
Get through the 'Lash' trial cave easily: Go down the first staircase, then use the shift glitch and go up the staircase and you will be near the mercury djinn, then you can go through the avalible doorway after shifting again and you will be in the boss room. (originally found by lelouis)
Treasure...no, wait...psynergy stone glitch: In the first desert, there is a treasure chest disguised as a rock(right by the exit near Alhafra). If you use the shift glitch before reveal, the treasure chest will be treated as a psy stone and when you pick it up, it will restore your pp, then vanish.
Post any I've forgotten or haven't found.
