The symbol "ね" (ne) in this text is a Japanese particle often used at the end of a sentence to seek agreement or confirmation from the listener, similar to adding "right?" or "isn't it?" in English. In this context, it indicates that the speaker is looking for confirmation or agreement about the statement they just made. So, the sentence could be interpreted as:
"What do you mean? Recall was never a savestate system or anything like that, right? It just takes screenshots."
I figure the sentence is perfectly understandable with or without it, but it's a fun little extra for anyone that knows some Japanese. Besides, this is the internet, why keep ourselves bound to just one language, ね?
Imagine if you had a bunch of screenshots of every update you installed. You could compare those dates with the official release dates and figure out if your computer was a test subject.
