Hello everyone!

I've been following speedrunning for about 3 years now, but I've never done any speedrunning, myself. I'm going to be attempting a couple of games from my childhood that have some records I think I may be able to beat (with a lot of work lol)

My question, however, is those games are for Playstation 1, but all the leaderboards (and the search feature under the Games tab) only show PS2. Can I run these on PS1?

Thanks!
