After installing the new PCB in my fightstick, I tested it on my PS4 with SF IV and it worked great, I’ll test it with SF V later today and see if it has legacy support. I had to move some of the connections around and use the “gamma” Fightstick setting so that R1 acted as a heavy punch and everything mapped correctly.
