... (say, because you're a PAL player and your PC sucks), which category would you submit it to?

PS4 Any% No Slots if you also don't want to use Cait Sith's Limit Break. If you want to use Slots and no boosters, you are out of luck as there is no category specifically made specifically for it.

Ah, cool, okay. I was distracted by the title and didn't read the rules properly, sorry.
