So, I just defeated Shotmaker and was trying out my new keycard on nearly all closed doors I knew of when this weird thing happened. Apparently, everytime I exit the elevator, at any floor except the basement, the game triggers an alert, even if I am not being spotted at all, and I can't get rid of it. If it helps, I'm using blueMSX emulator on PC and I'm using save states instead of regular saves (as these don't seem to work).

Can anyone help me?

Edit: Probably, this is posted in the wrong place of the Forum. I am new to it so I don't really know where it should be. Feel free to move to wherever it should belong to.
