Emulator

See the attached video to see a demonstration of these issues.

1. The first button clicked to start iterative input mapping stays highlighted blue for the entire iterative input duration, whereas the highlight should move to the current button that is being mapped.
2. The red indicator text trails behind by 2 input buttons. For example, if I input A, B, and then get to X, A's button text will now be in red, and when I get to Y, now B's button text will be red.
3. Iterative input maps joysticks differently, leading to problems (at least with the controller I tested). It seems to use -+ axes instead of the normal + or - axes, which makes the joystick off-center (see video for a demonstration of this). For example, when I map my controller normally I get "Axis Zr+" for down on the C stick and "Axis Z+" for right on the C stick. When mapping it with iterative input I get "Axis Zr-+" for down and "Axis Z-+" for right.
4. The mapping window is very laggy during iterative input mapping. If I only want to map the Buttons column (A,B,X,Y,Z,START) and finish and click Close on the window, it takes a number of seconds for the window to finally respond and close.
