help extracting a .dat file

[aviancompatriot]

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
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:

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

Enjoy ripping
