Unable to Use D-Pad w/ GBA

[ploderup]

Hey all! I'm a little new to the whole RPi emulation scene and would appreciate some help getting my GBA emulator setup. In order to easily use my 4-button arcade joysticks with games requiring analog joysticks, I configured the devices as if they were analog (in "Configure Input"). This meant that no changes needed to be made for N64 or PSX games.

For consoles pre-analog joystick, I was able to enter into RetroArch options (by pressing Select+X during gameplay) and enable the option under Quick_Menu > Controls to convert Analog to Digital. This worked for MAME, SNES and NES games. However, after enabling the option for the GBA emulators (I tried it with each one), I was still unable to register any directional input. Any advice on how I might fix this?

Thanks in advance,
