Windows version wishlist

[Monroe88]

A few things related to the Windows version of RetroArch that I would like to see eventually:

• Rumble support for the DirectInput joypad driver. Implement the equivalent function of xinput_joypad_rumble (https://github.com/libretro/RetroArch/blob/master/input/drivers_joypad/xinput_joypad.c#L454) into dinput_joypad.c.

• RawInput input driver for keyboards and mice. (https://github.com/libretro/RetroArch/issues/936) This one has been done: https://github.com/libretro/RetroArch/blob/master/input/drivers/winraw_input.c

• Improve the Direct3D 9 video driver. It is missing some shader features that the OpenGL driver has, like shader parameter support. Possibly add support for Direct3D 9Ex functions as well.

• DirectDraw/Direct2D video driver.

• WASAPI audio driver. The driver should support exclusive mode output so that RetroArch can bypass the Windows mixer to allow minimal audio latency. (https://github.com/libretro/RetroArch/issues/2771) This one has been done: https://github.com/libretro/RetroArch/blob/master/audio/drivers/wasapi.c

• WDM-KS audio driver. Same as above but for supporting Windows XP or earlier.

• Expand the Win32 UI that is already partially built in. Perhaps add some settings dialogs. (https://github.com/libretro/RetroArch/blob/master/ui/drivers/ui_win32.c)

Retroarch has an OpenAL audio driver. Theoretically that can be used to bypass the Windows mixer. (I have no idea how Retroarch uses it).

I will mention this:

• Improve Controller Remapping with images to really comprehend what is the command you have to press and images for a SNES controller shape and a shape for those controllers with 6btns or 8btns in the front and no shoulder buttons. (Arcade Sticks, Saturn / Genesis gamepads, MadCatz Fightpad, etc).
