GameSir X3 diagonal analog movement not working

[pivorsc]

Hello,

So i recently purchased myself GameSir X3 and i noticed that i cannot move in diagonal directions (up/right, up/left, etc.). The way i map PSP controlls is that left stick mirrors d-pad and right stick is mapped to PSP stick, and for some reason i cannot use diagonal directions with left stick.

I have no issues with some cheap bluetooth controller that looks like generic playstation controller, theres also no issues with any other game or emulator, its just PPSSPP specific.

Is there a way to fix or workaround this?
Thank you in advance
