rem  Heroes Rogue - Simplified Chinese Installer
rem
rem  HOW TO USE:
rem    1. Copy this file into your Heroes of the Storm install folder
rem       (the folder that contains "Heroes of the Storm.exe")
rem    2. Double-click it. That is all.
rem
rem  No parameters. Nothing else to install.

rem  tested 2026-10-05: gh-proxy.com ~24 MB/s (fast), ghfast.top works but slow (~0.7 MB/s)

rem  ==== installer self-update ====
rem  SELF_VER is this script's own version. Bump it whenever a new installer is
rem  published; the SELF_VER inside the downloaded release asset is compared against it.
rem  No state file on disk: the version lives in the script and nowhere else.
set "SELF_VER=0.2"
rem  SU_CHECKED is set once the version check has run at least once, so the
rem  header can say so instead of showing an empty state.
rem  SU_LATEST holds the version reported by the release feed once checked;
