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.
