Description
Region of the PSVita eMMC where perconsole info is stored.
Location
Idstorage data is stored at first raw partition (code 0x1). Use [2] to extract.
Structure
On PSVita, max 993 leaves exist. Many leaves are empty, 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.
