Just missing hc7 now, aka Victor HC-7.

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.

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

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.

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.
