# test.sh - headless test of a demo OMF. Boots MAME, drives the
# Finder to launch the demo, waits for the demo to reach its event
# loop, injects a keystroke to wake it, then reads back the
# trailing marker at $00:0070 to confirm the demo ran to completion.
#
# Usage: bash demos/test.sh <demo-name>
#
# Expected outcome: $0070 reads back as $99.
