A hacker named katsu recently released a method for dumping Vita games (http://wololo.net/talk/viewtopic.php?f=64&t=36827). As a developer, I am completely against piracy, but as a reverse engineer I can’t shy away from taking apart perfectly working devices. However, most pictures I see of Vita game carts taken apart show the game cart casing damaged beyond repair or completely destroyed. I managed to take apart a game cart and put it together with no obvious signs of damage, and I thought I would share my (simple) method here.

If you take a look at the top right or left corner of the game cart, you can see a line of where the two halves of the plastic was glued together. Locate the upper left corner and, with a sharp knife, push the blade into the line on the corner until you have a small dent. Then, move the knife downwards and wiggle the knife until you loosen the glue for the entire left side of the cart. Then keep moving the knife down and when you hit the bottom of the cart, turn and lose about half the bottom edge of the cart. Now you can use your fingers to spread the two halves apart (but be careful not to use too much force and tear the glue from the other two edges), and you can either shake the memory chip out or use a pair of tweezers.

If you were to follow katsu’s pinout, you need to solder to the copper pads. A trick for doing so is to first flux up the points and then melt a pea-sized blob of solder in middle of all the points. Then take your iron and spread the blob around until all the pads are soldered up. Then just make the the remaining blob is not on top of any copper and you can easily remove it.
