As discussed in libretro#5357; controller_patcher is now optional. It's
off by default; though this could be changed with a simple makefile
tweak (ENABLE_CONTROLLER_PATCHER ?= 1, perhaps?)
To re-enable controller_patcher; append ENABLE_CONTROLLER_PATCHER=1 to
your usual make command.
controller_patcher was the only user of c++ constructors in the Wii U
port, so you'll need 26a006c in your tree otherwise you will have a
blackscreen on startup.
Oops! Didn't do this quite right the first time round.
This commit fixes RETRO_DEVICE_ID_POINTER_PRESSED, which would always
return 0 due to to an implicit case to int16_t. Basically, we'd do
(val & 0x00080000) & 0xFFFF; which would return 0 every time. Fixed that
by wrapping it in a ternary. Yes, I know we could use a rotation, but
for a boolean value it really doesn't matter.
I also rewrote scaleTP to deal entirely in integers. While the
floating-point math was theoretically faster on PowerPC; it gets awkward
to cast -0x7FFF to a float.
Speaking of, the driver now actually conforms to the libretro API. Not
sure how I managed to not see the spec; but hey, now its fixed.
RETRO_DEVICE_POINTER_ID_X/Y will now return values between -0x7FFF and
0x7FFF like they're supposed to.
Big thanks to @r-type for hounding me to fix this.
Partially addresses #5294; we still need mouse emulation.
This hopefully fixes the issues when you try to use 2 Controllers with
the same vid/pid at the same time.
Tested with 2 DS4 controller via the Hid to VPAD Network Client.
Adapters with multiple ports (like the official GC-Adapter) are still
working
Allow using the Gamepad's touch screen as a RETRO_DEVICE_POINTER.
Methodology could use some work, had to add an extra axis to
joypad in order to get the data transferred into the input driver.
Feel free to change this.
Needs to emulate RETRO_DEVICE_LIGHTGUN to really be useful.
Potential for Wiimote IR in future.
Partially addresses libretro/RetroArch#5294
