Left and right not working on fba_libretro

@0zzy because they probably had analog input devices which are mapped to either the left or right analog stick.

@0zzy Recalbox is not meant nor configured to be used with keyboard anyway, you need a gamepad.

@voljega y are right, keyboard is not the best controller, but i'm testing it
@paradadf: if i use a ps2 controller i think i could move in both directions but in my final setup i will use gpio with arcade buttons, so how can i reconfigure them?

all I'm saying is keyboard might simply not work where a gamepad would

[0zzy]

@voljega if i don't have a gamepad but an arcade control panel? i'll check

arkanoid or chase hq, out run

Original hardware had a wheel, don't expect to play them properly with a d-pad. I would recommend to either find a way to have analog controls in your setup or drop games using those controls (most of them are racing games but there are a few exceptions like arkanoid or after burner)

@barbudreadmon you are right, but if the same game works in mame, why not let it work also on fba_libretro.

i'm trying to marge these 2 systems, i don't want both, but some roms for wich controls works on mame, does not work at the same way on fba

Because that's not possible, fba doesn't have an internal osd to configure inputs like mame, so i have to define the best possible default controls and let the user use "Quick Menu > Controls" if he wants to change them within the limitation (retroarch won't allow changing from analog to digital, neither the reverse).

Anyway i don't really understand your point, you are basically saying that since mame allows inept controls for a game, fba has to allow it too. Should i add mouse support for platformers then ? I'm pretty sure mame allows it.

Ah ok, thanks!

I read that there is a bug in kernels 4.4-4.8 that messes up the analog axes. The d-pad works as intended though.

Adding this to your CFG controller file should fix the problem:

input_l_y_minus_axis = "-1"
input_l_x_plus_axis = "+0"
input_l_y_plus_axis = "+1"
input_l_x_minus_axis = "-0"
