i don t now, i would just a program that save a string (for save a hero and play on bnet after) into a .txt file, because the string is very long (80 carac at least) ^^
Although it may seem like a simple task, writing a program to read memory and record its contents in a text file is a phenominally hard task, especially if you have no background in programming. Learn a language first, I'd recommend Delphi or C++. You can get a book on the subject. Once you've done that, and know how to read from memory and output as a .TXT file, then come back and ask for aid.
