Hello Absol,
It does.
(But not with the F1 command.)
Whether it's joystick or say, official Xbox controller..
I'd first check out Bearadactyl Prime's nicely written guide here.
It involves using the program AntiMicro, which is free, I tested on multiple platforms it works with Spork good. (and is good_)
I've took the the time and confirm that Spork does work with JoyToKey6.1 as well, but it's moreso a free trial. It's USB support. If you already had it, the same settings work and config with Pokemon Reborn. Like with any download or freeware, but be more careful on this one.
I tested with *playstation TTX usb ps3&pc controller.
If you're still interested or if anyone needs help, I can share or upload my settings here.
between those two or any more questions regarding, likewise
