Hello rathena. A time ago beret posted the packets of a system in the forum of hercules, and the topic was hidden, I could see the content before it gets hidden and I found it interesting.    This system allows you to add items in the cash shop with the day and time to insert and time that the item remains in the shop before it was removed.     Packets by Beret: // packet = 0x9ac struct PACKET_CZ_REQ_CASH_BARGAIN_SALE_ITEM_INFO { /* this+0x0 */ short PacketType /* this+0x2 */ short
