Hey guys,

Been trying to figure out what's going on with particular games (like Dissidia) which have problems with diagonal input.

Essentially, it's been covered in this post and several others, but it's been two years and nothing's been resolved so far:

The problem is as thus:
My particular gamepad (Gamesir G4s) has an analog stick, and the stick's input limit is a circle (so when you push it to the directions and go all around, it'll make a circle on the Analog Tester in PPSSPP).
Analog in PPSSPP actually uses a square to measure the limits.
What this means, is that my gamepad's analog circle limit does not reach PPSSPP's analog square's limit. Subsequently, in games like Dissidia, where it requires the furthermost edges to be reached, I cannot move diagonally.
In games like Kingdom Hearts, the diagonal does not cause as much problems, because it still registers diagonal input that doesn't reach the corners of the square, but in some other games this diagonal problem is an issue.

Apparently EXPSE also had the same issue, and had this to say about it:

Quote:Physically, the stick rotates in a circle. Driver wise, the stick can move in a circle, or in a square. API wise, it does whatever the driver tells it. Application wise, it does whatever the api tells it(unless otherwise scaled differently in the applications code)

Programmatically on the actual hardware game console (and the emulator), it expects that pushing the stick diagonally will be able to hit the max postive or negative value for the combined axes which are -127 - 128 between X and Y.

Currently, the released version of espxe takes the range as provided directly from the driver with no scaling up of the value, so when you push the stick in the diagonal's the most you can get is a combination of -93 - 93.


So basically, when the console expects to see X-127 and Y-127 (Down-Right) it only sees X-93 and Y-93 instead and the game either ignores this input depending on its deadzone, or simply walks instead of runs.

Does anyone have an idea to fix this, other than just playing with the D Pad?
Thanks
