Collection:
If you press C while inspecting Inv, you can get Inventory List. |
Use inspect subcommands recursively.
Example: While viewing Inventory List, assign ego address to owner. ego, owner are
objects. So you can collect all treasures at any time. Write ego in lower case.
You can inspect hex address of memory
(Example $3455) or any object (Example: Sound)
