But I don't know how to do it ;; Does anybody know how to change the activation button for codes? Specifically from L+R to Select?

This is getting ridiculous, after much searching and trying I cannot find this code. I need a code that either gets me 900x EV wings or gets me 900x the first item in my Medical bag. This code is for pokemon White and I need to be able to use Select. My R button is broken ;;. I found a code on a bunch of websites, but it is completely failing on me and I don't know why.
