Just wanted to see if someone here (Randy hopefully

) can confirm my set up please.. and you have to be a bit gentle with me, it's been a while since i have played with mame.

I am trying to add a pause and esc button on my cp, yeah yeah i know, not meant to be but when the wife calls you cause your 2yr old has done something that I have to deal with, i's needed .
I have this device
http://www.groovygamegear.com/PDF/GP40_Eco_ST.pdf and I can see pause is pointing at K. But where is esc Is this cancel which is pointing at J ??
I have since been into the gamepad (through control panel) to check that all buttons are working ok. I pushed the two im trying to use as pause and esc and they show being hooked up correct but don't work in game play.
I'm stuck, any help in getting this going would be great.
Thanks
