[Cause]
The pressure application motion command Press_m[SD=,P=,SEL=(,)] cannot be used with $sgsysdg.$uga_idx4gb=false. With this instruction, gun B and gun A data are shared.
[Countermeasure]
To use Press_m[SD=,P=,SEL=(,)], set $sgsysdg.$uga_idx4gb=true. Alternatively, using Press_m[SD=(,),P=(,)] allows the $sgsysdg.$uga_idx4gb setting to be ignored.
