LilyPad 0.10.0

[jesalvein]

I was doing some research on trying to get my PS2 GH guitar to play on Rockband, but ran into the "need to connect Mic" issue. I saw that people were using this Lilypad plugin. I got the newest download and unzipped it into my "QtPlugins" folder that I found in the PCSX2 Files. I booted up and then tried to find the drop down option every video refers to "Config" and I dont have that option. 

Would someone know the next steps to take in my case above?

use 1.6.
won't work on 1.7 for now
