testing with the snes program.
[L eft] [R ight]
L R X B
All alone works ok
U+L = Ok
D+L = Ok
D+R = need to press many times to get Ok (only register Right). Note: when pressing both and the buttons are registered correctly, in less a second the Down key is released automatically.
U+R = Cannot get Ok pressing many times. Using Stick to pass this.
A+X = Only X
A+B = Ok
X+Y = Ok
Y+B = Ok
X+B = Ok
Y+A = Only Y
X+A+B = No reaction
A+B+Y = No reaction
B+Y+X = No reaction
Y+X+A = No reaction
B+Y+X + D-PAD = Appears to keep working, but curiosily, D-PAD Down+Right works well (register more times and keep pressed)
Other combination of 3 action buttons + D-PAD, have issues.
pressing A+B+X+Y = no reaction
pressing A+B+X+Y + D-PAD = only works UP and Down
Testing with L1 + R1 triggers i have the same issues (apparently, tirggers don?t make any difference)
Testing with L2 + R2, triggers, apparently L2 generate issues on D-PAD when pressed (some buttons don?t register press).
for now, i need somebody that can confirm have issues too with D-PAD to get clear about is a specific problem of my device or a generic problem.
note: the behavior of the buttons when pressed make me to think this is a software problem. if hardware problem, then D-PAD Down + Right never will pass on this test, but there are sometimes when button press can register correctly.
the combination B+Y+X + D-PAD Down+Right may confirm the above, because if i press B+Y+X and then press Down + Right, if the progran don?t register the pressed buttons inmediately, if i wait for some time (half second) the buttons will be registered correctly as pressed (is the opposite as when i press down+right without B+Y+X, that will unpress after a moment)
