# runGnoMameSmoke <omf-path> <marker1> [<marker2> ...]
#
# Launch an already-built GNO/ME OMF under real GS/OS 6.0.4 + GNO in
# headless MAME and assert that every <marker> matches. Each marker is
# a single `addr=hexValue` token in the runInGno.sh `--check` syntax
# (e.g. `0x025000=C0DE`). Multiple markers are passed positionally —
# the function does NOT split on commas, so a caller wanting two checks
# passes two separate args.
#
# Exit 0 on all-match, 1 on any miss. Mirrors tests/lua/runLuaTest.sh's
# pattern of "run program in emulator, then assert canned markers";
# scoped at GNO instead of bare-metal because the C++ smoke / cxxstdlib
# / cursor work needs a real OMF Loader path.
#
# Required prereqs (caller should pre-check or let this function die):
# tools/cadius/cadius
# tools/gsos/6.0.4 - System.Disk.po
# tools/gno/gnobase.po
