Arcade 1UP MSH Countercade - Analog Stick not working with PPSSPP

[E-D@N]

Hey All,

I've bought this countercade and it's great!
Modded it using this guide and now working with Batocera and 6 buttons support:

PPSSPP also seems to be running great, tried some games and it's running pretty smooth, but.. Only the 6 buttons are working, the analog arcade stick is not - I'm able to start a game, jump, kick.. but can't move

Can someone help me troubleshoot it? Maybe someone already fixed it, or tell how to configure it by editing "controls.ini" or something else?
I can't launch PPSSPP within Batocera in Countercade - so I can only edit files in my PC, maybe there is a way to record the input of the controller and dump it?

Thanks in advance!
