Speedhack is a clientside pointer modifcation:
DWORD speed;
DWORD* dwSpeedpointer = (DWORD*)0x006F3840;
MemcpyEx((DWORD)&speed,DWORD(((DWORD)*dwSpeedpoint er)+0x00004B14),4);
Depending on what the Admin setted up for the maxium speed limit, you can increase this via cheat.
Attack hack / splashbot and picking and beheading are based on Packet Hacks (well Splashbot can be done as Keyemubot, wich will also work again then), but other Public hacks, wich are based on the fact that you are able to Send Valid Packets to the Server, like you can do with Clean, R11 (Kosp), KoemV1 or KoemV2 does not work with MadKnight Protection (at the moment, until it is cracked).
So atm you cant use PacketHacks on Hiddenkal, Xtremekal, Xiuonline, Acidkal until a SendMethod is finished, wich could be called "MadSend" ^^
