| 15 | * Memory hooks have two purposes: | ||

| 17 | * texture forwarding and memory breakpoints for debugging. | ||
| 18 | * 2. To allow for the implementation of MMIO devices. | ||
| 19 | * | ||
| 20 | * A hook may be mapped to multiple regions of memory. | ||
| 21 | * | ||
| 22 | * If a std::nullopt or false is returned from a function, the read/write request is passed through | ||
| 23 | * to the underlying memory region. | ||
