This is a Bash script that displays checksums for ROM files. It can operate on archive files (currently ZIP, 7-ZIP, gzip) and run recursively to display the contents of a directory tree.
Project homepage: https://github.com/hippie68/rom-checksum

Motivation: I like to operate on the Linux command line but I found it tedious to search and check manually which ROMs are compatible with romhacks. So I wrote this script which makes such tasks much easier. Maybe someone else will find it useful, too.

7-Zip already has a feature for that. Furthermore, Linux has 'md5sum', 'sha1sum' and 'sha256sum' to calculate checksums. What is so special about this tool? Does it display the checksum linking to the game's title by a list of checksums?

I believe simplicity, built in recursive and archive content checksums are it's USP.

Most of what it does can be done in other ways e.g. use find to pipe the contents of folders into md5sum and output an md5 file, but I can see use for an easier way to do it.

That said, I could see this potentially being more useful if either it can verify the roms against a database or it becomes less games focused so it could be used to e.g. detect bitrot.

For me the biggest advantage and reason to create the tool is that it not only displays mere file checksums but also "ROM checksums", the latter which are for the headerless part of headered ROM files. Currently it does so for NES ROMs, and I could add more ROM types if there is demand. The output closely follows the checksum list style found for romhacks on romhacking.net. The hack authors have different preferences for which types of checksums they put there. And sometimes it's not clear whether their checksum includes the header. So for headered ROMs this tool lists the headerless checksums, too, and if any of them matches, at one glance I can be sure the hack will be compatible. That's all there is to it.
