Hi, here is some original files and encrypted files.
https://www.mediafire.com/?8xzxiedgm6b6jmt It would be appreciate someone could decrypt it.
I think comparing BGM or ED6_LOGO might be help. And here is information.

"Hi, I checked the encrypted files, and I think they can be decrypted. The encrypting algorithm is actually quite simple. It reads 8 bytes from the original file, does some kind of binary operation on this field then writes it to the output.

For example, in the encoded file, 8 bytes of 0x0 always becomes 0xE25610A8CF5E9B4D, 0x2F5F5F5F5F5F5F5F2E5F5F5F00000000 (see the end of the dir file) always becomes 0x7C6E8C987BCD24611586F8FB36AB0249.

The problem is of course figuring out what happens with these 8 bytes. While the algorith looks simple, I'm not a cryptography expert, so it might be faster to search for somebody who knows what can be done with this. I tried writing a very simple bruteforce program, but it will take about 2302,74 years to finish (checking 2^64 numbers takes time).

There is also an interesting thing, the size of ed6_dt00.dat (encrypted) is not a multiple of 8, and there is a half-encoded (?) 4 bytes at the end. You can see the lots of encoded nulls before it too.

Well, maybe you can figure out something. Good luck! :)"

How did you get the encrypted files?
Does the game come with some kind of a launcher?

I received packed files from someone and I unpacked it then I got encrypted files.
It used launcher, however it doesn't service now. The game company became bankrupt.

Here is more information.

working directory: c:\program files\aruon\frog\game\ed6fc
executables:
- ed6_win.exe
- config.exe
type:
ed6_win.exe: wdp,type-1, frog
config.exe: wdp,type-2, frog
code: rT5EtsTFPHdblY PuVpvquFIc4mlZJl0HgP1/XHdR4XzVMmU0iNrJjwgI 7j7dIUUQz0AYqgcNQpVV40LLUfuBdG8sYNYUJRqP9RI8DB4kJSLMM7ch22F6A4D2GyETJPE4Az9OCmCfM3XZppI/v07Kmpbcqiq47mNh/qfSXAaiogivv fu0P6AZUVgEGAA==

I wonder what the code means.

Can you send the files from the launcher? It might be possible to find the encryption function in there.

That code looks like a base64 encoded file. But after decoding, there's nothing readable inside:

I tried using this file as a key for encryption scan, but no correct files came out.
