Gamepad binds being recognized on configuration, but not ingame

[afancyname32]

Recently, I installed PPSSPP version 1.6.3 on an old blackberry, using the builtin Android emulator (latest version for blackberry, 0.9.9 had sound issues), and when I entered the mapping section, I was delighted to find out the keys from the physical keyboard were recognized. I thought everything would work, since mapping keys worked fine, but when I entered the game, no key presses were registered, and the controls didn't work. Is there any way to make it work as it did on the configuration?
