Nv Items — Reader Writer

The writer performs the inverse operation. It traverses an in-memory item tree, calculates required buffer sizes, and flattens the data. Critical features include:

save.write_items(inventory, backup_original=True) nv items reader writer

nv_status_t nv_write(uint16_t id, void* data, uint16_t len) 
    if (len > MAX_ITEM_SIZE) return NV_ERR_TOO_BIG;
    uint32_t crc = crc32(data, len);
    nv_item_hdr_t hdr = .id=id, .len=len, .crc32=crc, .version=++global_version;
    return atomic_write_to_nv(&hdr, data);

inventory = save.read_items(player_ref_id="00000014") The writer performs the inverse operation

for item in inventory: print(f"Item: item.name, Count: item.count, Condition: item.condition%") inventory = save
