Are you sitting on a bunch of old DOS-era SNES ROMs with weird, abbreviated filenames and dubious extra bytes? Does the fact that you're the kind of person who would still have DOS-era SNES ROMs in your possession haunt you on sleepless nights? This tool can help you with one of those things.
snes_scrub searches the input directory (the current directory by default) for files with .sfc, .smc, or .swc extensions, and compares their SHA1 hashes to the no-intro.org SNES dataset. It will also try and hash the file minus the first 512 bytes, in case the ROM has a vestigial SMC header prepended. Any matching no-intro files are copied to a output directory (./scrubbed by default), renamed using the no-intro.org filenames and stripped of their old SMC headers, if they had any.
You have to have Python 3 installed. If that's good, then:
python3 -m pip install snes_scrub
From any directory with SNES ROMs, simply run snes_scrub and any ROM files in that directory will be processed and stored in a subdirectory called scrubbed.
If you want to use different input/output directories:
snes_scrub --input /example/rom/directory --output ./clean
will read files from the /example/rom/directory directory and put cleaned files in a clean subdirectory off your current working directory.
snes_scrub --help gives detailed usage info.
Theoretically, on Linux/MacOS:
make build
If that succeeds, you can install directly from the local wheel file using:
python3 -m pip install dist/snes_scrub-0.1.0-py3-none-any.whl
