# ndstool — extract/pack Nintendo DS .nds ROMs (ARM9, ARM7, filesystem).
# https://github.com/devkitPro/ndstool
#
# Build:
#   docker build -f Dockerfile.ndstool -t mkjs-ndstool .
#
# Full extract + object ID report (needs test/mkds.nds or pass ROM path):
#   chmod +x scripts/extract-mkds-rom.sh
#   ./scripts/extract-mkds-rom.sh test/mkds.nds
# Without Docker:
#   npm run extract:rom
#
# Manual ndstool extract (writes into mounted directory):
#   docker run --rm -u "$(id -u):$(id -g)" -v "$PWD/test/nds-extract/out:/rom/out" \
#     -v "$PWD/test/mkds.nds:/rom/game.nds:ro" -w /rom/out mkjs-ndstool \
#     -x /rom/game.nds -9 arm9.bin -7 arm7.bin -d data -y overlay
#
# Interactive shell with ndstool on PATH:
#   docker run --rm -it -v "$PWD:/roms" --entrypoint bash mkjs-ndstool
