FFG.exe

Im making Atom fishing server emulator. Check my last_server.py. The CMD= packets there are wrong. i need you to decompile FFG.exe and find all "CMD=" packets and make full list. also Check CMD=180, it has optids 2-8. CMD=220 opens world map (optid=3), CMD=900 opens Storage (склад), CMD=172 is not for perks, it's for прикорм. CMD=200 opens shop. The shop contents storaged in GameData.pkg. Find all other CMD's and optids and make full list with full structure and functionality. FFG.exe (it's Client.exe).

im sure you. ive made parsing test of all  "CMD=" 220 is for opening world map. i tried it in client as an answer for 180 optid 3. It's opens world map. 900 opens storage. 200 for shop. 172 opens создание прикорма. I test it in game.

Corrected CMD=180 Handler:

def handle_cmd180(srv, conn, payload):
    kv = parse_kv(payload)
    optid = int(kv.get("optid", "0"))
    print(f"  [OPT] CMD=180 optid={optid}")
    
    if optid == 2:
        # Bait/Weapons - CMD=200 response
        print("  [OPT] → Bait/Weapons → CMD=200")
        srv.send_pkt(conn, cmd=200, payload=b"bates=\r\n", flags=0)
        
    elif optid == 3:
        # World Map - CMD=220 response
        print("  [OPT] → World Map → CMD=220")
        srv.send_pkt(conn, cmd=220, payload=b"", flags=0)
        
    elif optid == 4:
        # Tournaments - CMD=402 + CMD=950
        print("  [OPT] → Tournaments → CMD=402 + CMD=950")
        srv.send_pkt(conn, cmd=402, payload=b"", flags=0)
        srv.send_pkt(conn, cmd=950, payload=b"", flags=1)
        
    elif optid == 5:
        # Premium Shop - CMD=601
        print("  [OPT] → Premium Shop → CMD=601")
        srv.send_pkt(conn, cmd=601, payload=b"", flags=1)
        
    elif optid == 6:
        # Storage - CMD=120 (inventory sync)
        print("  [OPT] → Storage → CMD=120")
        send_cmd120(srv, conn)
        
    elif optid == 7:
        print("  [OPT] → optid=7 (unknown)")
        
    elif optid == 8:
        print("  [OPT] → optid=8 (unknown)")

Data Structures:

CMD=900 (Storage) reads binary:

// Header:
uint32 storage_id
uint32 field1  
uint32 field2

// Items loop:
while (has_data) {
    uint32 item_id
    uint32 field_30, field_34, field_38
    uint32 field_40, field_3c, field_1c, field_20
    bool field_68, field_69
}

CMD=200 (Shop) reads:

// Items loop:
while (has_data) {
    uint32 item_type
    uint64 price (field_30/34)
    uint32 field_40, field_3c, field_1c, field_20
    bool field_68, field_69
}

The main corrections needed in your last_server.py:

  1. CMD=180 optid=3 should send CMD=220 (not CMD=110)
  2. CMD=172 is for bait durability, not perks
  3. CMD=721 is the actual perks command
