The Disable Volume Warning patch doesn't work on 3.3.0.16 anymore.
I have created a new .patch file and patched the file in question (it's only 1 line in 1 file) manually.
It appears to be working as it should, the fix is the same but the content around it has changed.

I would like to submit this to he PM3 web catalog.

Q: Would it be better to update Ancelad's patch instead of creating a new one? If so, how can I do that? I cannot find any contact or git repositories for this user.
It seems they were active here not long ago, so I guess I'll just wait for them to see this.
But the general question remains: what's the best strategy here?
