Was just wondering why emulators are completely banned.

I know that spam pausing to save time is banned, but am I allowed to pause once or twice during a speedrun to select an item or do I have to have to use a to select items?
Edit: I just saw a run that pauses to select an item.

(OG post by zachfun1234: "While I was surfing the web and I found a download of Cuphead which I think is the 1.0 version of the game. This version is free and has no virus or malware just putting that out there. I was just wondering if I am aloud to use this version of the game or do I have to use the legacy or current patch version of Cuphead. Here is the download link to this version of Cuphead. <link removed>")

What you've linked is a pirated version of the game, which you can't really go around and post. Hence me deleting your message.

Now, you can technically do runs on that. There is no way for anyone to know if you're playing on a pirated copy, plus it wouldn't interfere with the run itself so banning it wouldn't make much sense.
That being said, it is discouraged. If you have the means to you should totally pay for the legitimate version and support the developers ;)
