I'm having an issue extracting specifically DLC apks from Madoka Magica the Battle Pentagram

Post by LarryKoopaTheHacker »

So I managed to get my hands on a few DLCs from Madoka Magica the Battle Pentagram in the form of pkg files I got from NoPayStation (which I extracted) and I came across apks, and for some reason, the dragon_ball_z_boz.bms refuses to extract these apks particularly, I tried to extract the only Madoka DLC I was able to get and it tells me "signature of 4 bytes at offset 0x00000000 doesn't match the ones expected by the script" and I don't know what to do, because they're clearly apk files, but they wont extract with the script (err, didn't test all of them, but I know the madoka_cos2.apk won't extract)

Any help with these files will be greatly appreciated

I saw another topic from you about the reimporting of this game (viewtopic.php?f=9&t=11103), so were you able to extract the files?

Sorry for the late response, Yeah, I've been able to extract the regular apks, but for some reason, the DLC apks just doesn't work. These are the DLC apks I have - https://drive.google.com/file/d/1dF7hme ... sp=sharing Perhaps it might need it's own script to extract it with that would be made specifically for the Battle Pentagram DLC apks?

Not sure what was the script you used but the file you provided (both idx and apk) are definitely encrypted, so not much we can do.

Oh darn, is there a way to decrypt them? I know there HAS to be a way I can get access to those DLC models from the Battle Pentagram like I can the normal ones. I just need the right tools for it. And the script I used was the dragon_ball_z_boz.bms since that worked for the regular game's apk files when I was able to extract those.
