Summary 04159: sgmast, sgmastc, sgmastj: Controller does not emulate correctly, game unplayable
Description The swing power controller (which rotates through 180degs) does not emulate correctly, i have tried a joystick controller, keyboard, mouse, and attempted to change the options, but whichever way I use I cannot get the power bar to go above 70% (=3/4 swing), hence the game in unplayable.
Steps To Reproduce this will become evident if you play the game,

The game's input for strength of swing should involve 6 bits, not 4 (as an 8-way).
Schematics clearly show that 6 pins off the connector deal with swing (d0-d5). Currently only d0-d3 are covered with the joystick setup.

I've attached snippet from service manual which details the pinout for the game.
