Issue of analog control in FB Alpha core

When I play the game using analog control in FB Alpha(e.g. Night Striker) I press the stick the right-end, it goes the right but eventually the left-end. (It’s same in press the downside but eventually up)

It seems like ‘overflow’ of analog axis.

It isn’t found in MAME cores and standalone FB Alpha program. Only in fba libretro core.

(used Windows 7 x64 + Xbox One gamepad)

That’s strange, i never experienced this on linux. What input driver are you using ?

used xinput driver. I’ll take the video that ‘overflow’ situation.

Oops. I forgot the video. but you can easily notice when you play and move up to the end Night Striker in FBA core with analog controller. (compared with MAME core)

Recorded video.

in FB Alpha core. When I stick slide to up(to go down), the player goes down but suddenly go to up to end.

in MAME 2003 core, the player goes down correctly. (no mentioned bug)
