it was easier to set up multiple controllers for an emulator twenty years ago
when you got your ROMs on a CD-R off a tarpaulin on the pavement outside a bowling club in Manchester, because when the internet screamed EEEE-EEEE-EEEE-EEEE-BRLGHBLRRBGHLEGHREE for forty seconds it'd still take half an hour to download Ghouls and Ghosts, when you had to start MAME from DOS, using multiple controllers was easier because at least you didn't have to deal with the emulator trying to help
two decades later these retroarch lads have put Clippy in your controller and I've spent literally five hours trying to figure out what the hell retroarch is trying to do, but I'm no closer to figuring out how to tell it to stop
