"Select" not working

[RYS]

Hello I am new to this site! I was having a problem with another emulator I have. In a game I am playing to use health is to press the 'select' button, which I have mapped to R Shift. I tried putting it to other keys and still no luck. I figured it was the emulator so I got me ZSNES. I am still having this problem and I cannot advance in my game and I am getting very aggrivated. If anyone can help me I would greatly appreciate it.
