OK I SWEAR I will try to get this slot problem ONE MORE TIME.
Someone can tell me where this line of code is:
ShowMenu (pPlayer, 0x7F, 0, 0, szMenu);
This noob tutorial writer just said "that 0x7F means that the slots 1 - 5 are open and can be selected..."
He didn't even say where this line is and how I can change the hexadecimal values or anything. So if anyone can find this line, serverside or clientside, I think this slot problem can be rectified once and for all.
