*''4 button joystick, while Amstrad supports only 2 is most probably the cause of failure to get all directions properly.''
''Tests have to be done with an old older 2 button PC analog joystick.''
''As while CPC era Joystick were perhaps less subject to exotic setting, more modern era joystick often had to feature their own drivers on PC (Win95+ era) and manufacturers often included more buttons, having to rely on non standards Pin-out setting.''
''Yet if you manage to find an old 2 button PC analog Joystick, and actually own a GX4000/Plus with the Tennis Cup 2 Cartridge, it's worth giving it a try for the fun of it.''
Also if you manage to get your hands on such Joystick, keep it.
