Hey SotN players & moderators, glad to be here!

I would like to ask if there's any problem on running the all bosses category using a original Playstation hardware and a original Japanese version of the game. I'm asking because i have these and would be great to be able to speedrun in the original hardware and game.

And last but not least, is there a Richter All Bosses category for the Saturn version? Am i able to run this category using a original hardware as well?

Thank you all in advance :)
