help extracting a .dat file - aviancompatriot - 01-17-2025

i've been meaning to extract some assets from this .dat file which come from this short doujin game
problem is i've tried multiple tools and none of them worked
dxarc? arc_unpacker? GARbro? neither one of these were able to extract the contents of the file,which i know exist due to the hex code listing some of the files inside[Image: Capture-d-cran-2025-01-17-172611.png]
i would very much appreciate any help given for me to figure it out

Have you tried Dragon Unpacker / HyperRipper?

dragonunpacker itself didn't work
but with hyperripper i had found some success
the images came out wobbly and weird

though the audio files came out decent though it came with a weird tick example
thanks for this tool though i feel there's something else i could use that could grant a cleaner rip

It seems like data is RLE compressed. You're lucky to get anything from this DAT file, because usually data is totally unreadable when it's compressed.

I was able to create a program that unpacks data from "Data1.dat" archive from "Re:Tiyoruga" game.

You can download it here:
https://github.com/bartlomiejduda/Tools/tree/master/NEW%20Tools/ReTiyoruga/ReTiyoruga_DAT_Tool

All the data was compressed. You can see my implementation of decompression algorithm here:

Enjoy ripping Smile

Everything is explained in the README file. You just need to follow the steps and you should be able to extract files. Smile
