How to Disassemble Vita Game Cartridges

A hacker named katsu recently released a method for dumping Vita games. 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. Continue reading

In order to locate the trace from the eMMC (aka the NAND), my plan was to take a broken logic board and remove the eMMC chip and use the exposed pads and trace it to a test point or something. Then take another Vita logic board (this time with the eMMC still attached) and solder wires to the test point and dump it with an SD card reader or something (as eMMC uses the same interface as SD cards). This is a complicated plan, but it’s necessary because I am not professional enough to be able to remount the eMMC (which is a tiny fine-ball-grid-array (FBGA) chip) once the trace is found.
