lr-ppsspp - how to get retroarch configuration screen?

[dinth]

Hey. This is a noob question, but i have checked the documentation and couldnt find an answer.
With all LR cores on my RetroPie i can access the configuration screen by pressing Select+X on my pad, except of LR-PPSSPP as none of Select+ combinations work in it.
Is there a way to set up lr-ppsspp in a same way as other lr cores?
