How can I remove chat messages from a replay?

Solution 1:

You need to download some MPQ editor, like Ladik MPQ Editor.

Here are the steps you need to execute:

• Make a new directory like C:\mpqeditor\
• Copy MPQEditor.exe to C:\mpqeditor
• Copy the replay to C:\mpqeditor\game.SC2Replay
• Create a new empty file with Notepad and save it as C:\mpqeditor\replay.message.events (make sure it is not replay.message.events.txt)
• Create a new file C:\mpqeditor\script.txt in Notepad and copy this code into it:

o "game.SC2Replay"
d "game.SC2Replay" replay.message.events
a "game.SC2Replay" replay.message.events replay.message.events
c "game.SC2Replay"

• Open cmd and exectue cd C:\mpqeditor. You might need to open cmd as Administrator for some reason.
• Execute MPQEditor.exe /console script.txt

You can even create batch job out of this, see original source for further instructions.
