-memchunkhdr = a data structure describing chunks of memory allocated by the ARM11 kernel.
-Here is some code describing the layout of a memory chunk header.
+This is the header that the kernel uses to implement the FCRAM heap.
-    struct MemoryChunkHeader {
+Size : 0xC bytes?
-        int num_pages; // size of this chunk in terms of small pages
-        void* next;
-        void* prev;
-        int unk1;
-        int unk2;
-    };
-The "next" and "prev" members are used to implement a linked-list. In fact, chances are this is actually a kernel object inherited from [[KLinkedList]].
