# verify-win16-tilebank.sh - Tile-bank gate for the Win16 port: proves the
# build loads the DOS bake (its stage is the same chunky 4bpp) exactly and
# refuses a bank baked for any other target.
#
# Runs TILEBANK.EXE on Windows 3.11 under DOSBox (scripts/lib/win16Gate.sh)
# from a scratch folder holding it and the DATA/tilebank its make staged
# from the host gate's fixture (the port makes the program's own folder the
# current directory). Its TILEBANK line in JOEYLOG.TXT must say PASS with
# both hashes equal to the host gate's and every other target refused
# (scripts/lib/tileBankGate.sh).
#
# Usage:   scripts/verify-win16-tilebank.sh
# Requires: a host cc, Windows on DOSBox (install.sh install emulator:win16);
#           build/win16/bin/TILEBANK.EXE and its DATA/tilebank (make win16).
