SDL deadzone configuration

[Augusto]

Hello Tux and Raine users.
Raine allow use digital pad and analog stick at same time. That's good.
In Samurai Showdown and KOF trying to make moves using analog stick it's not very precise because the value used for gamepad deadzone.
Is possible an option in Inputs menu to adjust the value for deadzone ? That would help.

I didn't put that as an option because sadly the arcade games don't handle precise joystick movements, it either moves or not. So I decided to take a huge dead zone in this case, it takes half of the moving area. Meaning a joystick returns values from -32767 to +32767 for its 2 axes, a move is valid if the stick has an absolute value > 16000 !

If you have a stick which still needs some dead zone configuration even with that, I'd say it's really broken at this point !

Now replacing this 16000 value by a setting wouldn't be hard, but well, it seems a little too much... !

Here the PS4 DS4 left analog stick has exactly that deadzone value that you are saying.
Testing in KOF94 is easy to do the moves charging and normal attacks. KOF98 has control more precise and is more hard to do the moves.
MAME has an good deadzone value and testing SF2HF is easy to do the moves. I not has tested MAME with Neo Geo games because that type of game I use your emulator.
If Raine has a way of adjusting the deadzone in rainex_sdl.cfg would be very good.

Well the time of cfg editing was mainly for the dos version, where adding an option to the gui was a nightmare. A good point of the sdl & sdl2 version is that the gui is redone, and it's much easier to add stuff, so no cfg editing required anymore.

Well I guess I could add something for the crazy guys like you... !

Done in git, notice that dead zones are not really necessary afaik in linux, at least all the joysticks I could test don't return anything when the joy is at its default position, which is the expected behavior but it means no dead zone necessary, but that's not what happens in windows at all ! That's why I added this big dead zone...

At least this way people will be able to fine tune this... !

It's in the inputs dialog, like mouse sensitivity, same principle, a slider.

Thanks for adding that feature !

Tested with latest version and works with PS4 DS4.

Now are more easy to do moves using analog stick 😃

Have an nice week.
