In this video you will learn how to find and call 2 internal functions inside Tibia MMORPG. First function prints white text at the bottom of the screen and second one sends a speech packet with certain message. We will use Olly debugger to find these functions, figure out their calling conventions and make a function prototype so we can call them using an internal C++ DLL.

Tibia is one of the oldest and most successful massively multiplayer online role-playing games (MMORPG) created by a small development studio from Germany called Cipsoft back in 1997. For more than 20 years now, players have been visiting the medieval world of Tibia. It was really popular back in the day and still is cause of it's unique look and user-friendly client. There are 4 vocations (roles) you can play. Druid, knight, sorcerer and paladin. Each has it's strengths and weaknesses in PVP and PVE. Tibia map is HUGE and there are so many spawns, quests and mysteries you can research that you will never get bored.

Tibia was always a nice target for bot makers because it has a big player base, no anti cheat and it was built with native C++ which makes reversing super easy. There are thousands of source codes and posts out there on forums dedicated for reversing Tibia. One of the more famous game hackers you all probably heard of is Nick Cano, which made his bot for Tibia called Xenobot.
