Emulator

I'm having a problem with a game: When I move the stick a bit up or down, even just 5%, the character jumps or ducks. That's something bad. So I tried setting the deadzone to 30%.

The problem is when I want to go right, let's say I move the stick 100% to the right and 5% up or down, the game detects this and the character jumps/ducks.

What I'm asking here is to have 2 deadzone settings, 1 for vertical and another for horizontal, so that when I move the stick 100% to the right and 5% up the game won't detect the 5% up.

I know there are ways to cirvumvent this like setting the up/down directions to other buttons but it would be nice to have this feature anyway.
