I have a question about rps on 1 and 2

I have seemed to come across or something two conflicting sets of info, and can’t find both, so I want to know if the rock paper scissors is identical in both games (1 and 2) and if they always were.
I’m not sure, but It seemed like the triangle switched and made sences and stuff or something.
Please let me know if you know and not just looked it up on wikipedia, cause I did and that’s not good enough.
Thank you.
