IRRST Shared Memory

This is the shared-memory for "ir:rst". The additional New 3DS HID data is stored here. The structure of this is similar to the HID_Shared_Memory sections.

The total size of this shared-mem is 0x98-bytes.

Offset 0x0

Relative offset	Size	Description
0x0	0x8	svcGetSystemTick tick-count output, for when IR module updates entry index0 in the below array.
0x8	0x8	Before the above tick-count field is updated, that value is copied into this field. Therefore, this contains the tick-count for the previous time that entry index0 in the below array was updated by IR module.
0x10	0x4	Index in the following array which was last updated by IR module.
0x18	0x80	Array of 8 entries, where each entry(see below) is 0x10-bytes.

IR module first updates index0, then index1, and so on. When updating the array when the index is already 7, the index is reset to 0.
