All in the title, I just bought it for my PS1, so it's PAL Duke Nukem for PS1, and I was wondering why it wasn't here ?
Wish you all the best !

Reason PS1 category doesn't exist is because there is no justification to add it in the first place,nothing stops you from doing runs on PS1 though and you might just make a case for it to be added.

Well that'd be great cause running a FPS with controller against everyone on pc is just bullshit, I mean unless we run on different categories it's useless ^^
