Basically, a friend and I want to get a Dual X-Arcade control Panel and mod it half Happ and half japanese. So i figure the happ parts will be no problem but someone told me the japanese ones might because of the size. I think i will need
Happ Stuffs (buttons joystick)
2 Ps1 Dualshock controllers
And the control panel
Has anyone ever tried this? Or for those whove bought the single panel and modded it with sanwa/seimetsu how did that go?
