Thanks for what you're doing man, you're the best

Tysm dude! You're a lifesaver

Did it change again? Still getting the This client is not compatible with the currently deployed server. error.

Edit: I see the bytes you are changing, and when I compare it against a working replay, I can see they are the same (offset 0x10 changing it to 0x86, 0xd6, and 0x55) but I'm still getting the error. Is there something else I'm supposed to be doing? If I'm reading this right, everything past 210 is data, so I doubt anything needs to be changed there.

Edit2: It definitely seems to be related to 8.20.1 patch that was released yesterday, I just can't figure out what exactly changed.

They added a server side check for replays, so this fix will not work anymore.

Does this still work? I see that @fredimachado updated to 8.30. Is there a way to get around the server side check?

I have replays from version 8.10, is there still a way to fix those replays? The newest command isn't working for me.

@fredimachado Is there a way to decrypt crypted replay data?

I'm sure it's out-dated now - Please can we get an update?

is it possible to get another update?

still, look no way to decrypt encrypted data. but can get public data the same as before
