# verify-win32-joy.sh - Joystick gate for the Win32 port: both sticks, every
# direction, both buttons and every release, driven through two virtual
# gamepads under Wine and read back from what examples/joy draws; then the
# pads unplugged while JOY runs.
#
# The port (src/hosted/win32/win32Backend.c) reads JOYSTICKID1 and
# JOYSTICKID2 through joyGetPosEx once a virtual frame, their X and Y scaled
# from the driver's range and buttons 1 and 2. Under Wine those come from its
# bus driver (winebus, through the host's SDL); the pads are Linux uinput
# devices laid out as Xbox 360 pads (scripts/lib/padGate.sh), the only ones
# SDL is let see. JOY runs headless under Wine (scripts/lib/wineGate.sh) at
# one window pixel per stage pixel, and window grabs go through
# tests/gate/joyScreen.c (scripts/lib/joyGate.sh). Removing the pads must
# leave both sticks disconnected, and Escape must then end JOY.
#
# Usage:   scripts/verify-win32-joy.sh
# Env:     JOY_SHOTS  also keep the screenshots in this folder
# Requires: Wine, write access to /dev/uinput, Xvfb, xdotool, ImageMagick;
#           build/win32/bin/JOY.EXE (make win32).
