PPSSPP does not detect L2 and R2 with DS4 controller

[expat1999]

Subject says it all, but to clarify, all other button/controls on the DS4 work perfectly, including the Analog sticks, but the L2 and R2 triggers are not detected when binding controls through PPSSPP.

Also important: I am running PPSSPP for Android from the Google Play store on an Acer Chromebook R11. My DS4 is connected via USB (Bluetooth connection is not detected by any Android apps on my device -- not an issue specific to PPSSPP by any means).

I do know that my triggers function, as I have tested them with another Android app from the Google Play store ("Game Controller Key Mapper", in case you are wondering).

I am unsure if L2/R2 are not supported by PPSSPP or if this is just a bug. (Although, why they wouldn't be supported is beyond me, if that is the case)

If you have any questions, just ask!
