i dont know if there are splitters specifically for the ps4 controller but there definetly are ones that are just female usb to two male usb that you could probably use. though i dont know if what you are trying to do will even work:P
i use slushy's retime tool to retime run videos uploaded to youtube. you can get it here https://github.com/Slush0Puppy/retime for video files on my pc i use the nsmbw load remover to retime my run because its quite light weight compared to aviutl i used to use
what do you mean with splitter? you want to plug 1 controller to two things?
why is src a community of necromancers
im not sure why your pc shutsdown but i highly recommend taking livesplit out of the rar :P
people can discover my small games?
its there for me
