lol, no. You don't need to know assembly at all to hex edit a DLL... if it's only to change character strings
Open the bot DLL, look for a string like "welcome to podbot", and change the characters so that it says "w3lc0m3 to my l33t b0t"
At some point it pissed off Count Floyd and he decided to hide the welcome message in POD-bot 2.5 by XORing it. There has been much less ripping attempts since then
