Hello there! This game only consists of a 5gb data.rom file. Can somebody take a quick look? Here's the first and last 16mb: http://*USE_ANOTHER_FILEHOSTING*/86cc4cd ... d69/rom.7z

Thanks for your help!

The directory tree is not handled, I was on rush and it wasn't clear.

Thanks a lot, luigi! Don't worry about the folder structure, I'm only after the music as you might have guessed.

Thank you for ROM extractor, then I want to extract script from some files.
These files seem to include script file.

They don't seem archives.

I hope it's okay to respond to an old thread, I didn't see anything about it in the rules, but it's not an archive. It's a single script file with all of the text included.

The problem is that it uses a custom character table somewhat different than base Shift JIS. Kanji and han/dakuten gojuuon are in base Shift JIS, but Hiragana and Katakana have completely different hex values.

With an edited Shift JIS table.


With plain Shift JIS

forgot to mention,
the game uses binary search so the entries need to be in alphabetical order.

looks like the script was written for Python 2.x by the looks of the print statements, but you should be able to
fix that error by adding parenthesis around all the print statements and just use Python 3.x to run it.

for example change this

Code:

print ''.join(lines)

to this

Code:

print(''.join(lines))

Sorry for bumping, but Switch version Higurashi has new data.rom that has at the beginning ROM2

Here are first and last chunk of file (Whole archive is 7.04 GiB big)
https://drive.google.com/file/d/1t9ebtA ... sp=sharing

If someone could update script (and if it's Python - please write in Python 3)

Also looking for a script for the switch version file above, please help us out. We'd appreciate it!
