Taiko no Tatsujin: Drum 'n' Fun! (Nintendo Switch) .bin files

[yjy581216]

Hello guys.
I tried to extract these *.bin files, but I couldn't find a way.

TaikoBinSamples.zip

At first, it was possible to unzip these files by simply renaming it to *.gz and It had single *.json data file in it.
But after game's update, they changed encryption for some reason. so I can't use that method anymore.

can anyone help me?

The 2 new files don't have any commonality between them which means they're encrypted with a cipher that doesn't use a form of substitution or the method is unique to the file name etc. In order to find how to open them you'd need to look into the game executable code itself would be my guess so you'd need to post the decrypted game as well (I'm not entirely sure how dumps work on the switch but I'm guessing there is some type of code signing you need to disable and not just retrieving the file itself.)

They are compressed with gzip

Code: Select all

get NAME filename
string NAME -= ".bin"
string NAME += ".json"
get SIZE asize

comtype gzip
clog NAME 0 SIZE SIZE
