# This preload script provides a subset of Win32API in a cross-platform way, so
# you can play Win32API-based games on Linux and macOS.
# To tweak behavior, you can set the following Win32API class constants in an
# earlier preload script (these are usually only helpful for debugging):
#
# NATIVE_ON_WINDOWS=false
# TOLERATE_ERRORS=false
# LOG_NATIVE=true
