Region of the PSVita eMMC where perconsole info is stored.


Idstorage data is stored at first raw partition (code 0x1). Use [2] to extract.


On PSVita, 128 leaves exist. Some are empty, others are unique, and there are others which are duplicated. All leaves are of size 512 bytes.

First 0x20 * 0x200 bytes of the IDStorage eMMC partition is the index table, an array of 2-byte integers, which maps idstorage leaf to idstorage index. To find the index of a leaf, go through the array and note index of the element with the value of the desired leaf. Then, seek to 512 * index and read out the leaf data.
