here's a little bit of powershell scripting for ye to get all ROM files (recursive) in the directory you're in, and calc hashes. I've used this to eliminate double ROM files I have scattered around on my disk...

#Get SHA1 file hashes from MSX ROM files
$files=Get-ChildItem -Recurse -Include *.rom
$hash=$files|%{get-filehash -Path $_.fullname -Algorithm sha1}
$hash|select hash, path|ConvertTo-Csv -Delimiter `t -NoTypeInformation|out-file .\romhashes.csv

start "powershell" (on Windows, eh)
set-location "your directory"

Paste above code on the CLI and you'll end up with a file called "romhashes.csv" which can be used for further automation of just open it in Excel.

On Linux (can be WSL on Windows) or MacOS you can use fdupes to find all duplicates quite easily (and even delete any duplicates interactively).

Yeah, but I've got many rom sets with different filenames. So I de-dup on SHA1 hashes Smile

fdupes does just that (well it may use something other than sha1sum, I cannot recall). It checks the contents of all the files and offers either an overview of all duplicates or an option to keep 1 of them (and you can select which one).

Ah, yeah I recall such software indeed. I'm a powershell dude, so I don't do ready made tools. haha.
scanning for doubles is interesting, lotsa machines have the same .rom files. funny. I'm cleaning my dirs as we speak.

After looking all around, I couldn't find this one:

Toshiba HX-34:
ROM: hx-34_disk.rom
SHA1: c88ef953b21370cbaef5e82575d093d6f9047ec6

Please, help me with this one.

The big problem on doing that, is it breaks many .xml, and they are a whole lot.

So when you run Catapult and perform a new scanning (Ctrl+T), you'll see a mess.

If you remove duplicates based on sha1sum (so on content), nothing will break.
