I don't want to be that guy but I don't think that your edit has it's place.
Like it says in the description, the whole purpose of locking this post is :
This question exists because it has historical significance, but it is not considered a good, on-topic question for this site, so please do not use it as evidence that you can ask similar questions here. This question and its answers are frozen and cannot be changed. More info: help center.
So the only reason why this question is being kept here it's for it's "nostalgia" value. If the question was simply off-topic and not locked, it would be deleted after some times and you wouldn't be allowed to edit your question.
Allowing you to edit your question would go against the off-topic and the locking purpose.
You see, if we would accept historical questions to be kept on the site without any restrictions, you would be allowed to edit it but the fact that we allow these questions to be kept here goes with the restriction that we cannot change the content of our answers no matter what.
Also, if people are really interested in knowing what is up with that emulator, they can naviguate your blog to find it, it's the first post in the feed.
Is it possible to edit a locked answer?
No it is not possible. Not even by flagging. Simply because it would go against the purpose of locking the question.
