# Slackware build script for snes9x

# Written by B. Watson (yalhcru@gmail.com)

# Licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.

# 20180611 bkw:
# - update for 1.56.1.
# - switch the UI from gtk3 to gtk2, as 14.2's gtk3 is too old.
# - add undocumented PULSE=no build option (in anticipation of 15.0's
#   pure-alsa-system).
# - add SDL2 to REQUIRES. technically, it's not truly required: snes9x
#   only uses SDL2 to support joysticks. playing with the keyboard/mouse
#   would still work without it. 15.0 is coming soon, and will have SDL2
#   in the core OS, so don't bother me about this decision.
# - update README, the snes9x_gtk build went away in 2010, no need to
#   mention it now. also add notes about upgrading from 1.55.
# 20171221 bkw: use --without-system-zip to build bundled unzip, instead
#               of adding minizip as a dependency.
# 20171213 bkw: update for 1.55.
# 20170302 bkw: use long-format github URL
# 20161015 bkw: update for 1.54.1. script has changed enough that it
# can't build 1.53 any more.
