I was waiting quite a while for Super Mario Bros. 5 (even though I knew that would not be its final name). The "New" games held me off for a little while.
When I use it as a slang i.e., "that is gay", I'm using it ironically from the word gay (happy, joyous). It has nothing to do with the other slang usage, for homosexuality. People seem to forget that.
It must have been a revision; mine has transparent 'A' buttons. I got it back when boot2 vulnerability was still a thing. I also have some classic controllers from the same era that have transparent 'b' and 'a' buttons, but opaque 'y' and 'x' buttons.
