Hello again, I would like to know how you can extract the contents of a .png file, it seems that is compressed with something, attached a few files. I hope you can help me.

Use this QuickBMS script, and you should get working PNG files (likewise with the ones Deathbringer posted in your previous topic). These images use a simple XOR for the first 16 bytes, by the looks of it, and literally has the key necessary to unscramble the header right at the beginning ("PLAYCRAB00000000"). Excellent obfuscation there.

Only problem is these PNGs are paletted with transparency (just like with the Pocket All-Star stuff that's on tSR already), so you might need to find a program that can import those properly.

Thank you!!! You saved me!

Another question how would it be for the "jpg" files? since there are also some with the same format. I try replacing in the bms that you passed me the png by jpg but it did not work for me. I attach some .jpg

Seems like those work just fine with the script, too:

Oh! Yes, work it, but when I use the script in this files especially didn't work. When I open in hex editor the first line is different. I upload the files.

Uh... Judging by the filenames, it looks like you ran the script on them twice. Make sure to only use it on files that don't have "_deXOR" at the end.

Yes, it works, the script does not support many files, and I was doing 1000 in 1000, thank you very much, you can close post.

Can this be viewed from a phone? Or do you need a computer. I'm using APK editor to see the assets, Res, etc...folders but I don't see the png files. Thanks.
