How do you add MF to a replay already done on a PC? I know you open the replay on Notepad, but after that what do you do?

When you open it in notepad, you'll see a line that starts with "NEWGAME". After that there should be a 0.

Then there is the number of matchframes after 0.

It should be like this " NEWGAME 0;[matchframes here]".

Change that number to what you want and you're done ;)

Ok, thanks!
