# This gives you a VIP card in PSO Episode 3 USA.

# This patch is only for PSO Episode 3 USA, which means it requires the
# EnableEpisode3SendFunctionCall option to be enabled in config.json. If that
# option is disabled, the Patches menu won't appear for the client. If this
# patch is run on a different client version, it will do nothing.
