GP32 Developer Seeks Advice On Sec*max

[cowo]

Hi
I'm the developer of YEX (http://yex.sourceforge.net) a UNIX manager for Samsung Yepp MP3 player. I need sec*max to get the songs played by the device. I'd like an advice: can I expect any help from you (you as a team of gp32 developers) on this subject or must I forget it and stay with windows software?
Please PM me or drop a mail, even if the answer is NO.

Your asking GP32 users about the Samsung Yepp MP3 player?

I really don't understand how we are supposed to help you?

He is asking about a sec*max encryption free library. I think is the same encryption method used by gp32 commercial games

I dont know about, sorry ...

Well I know a certain someone who 'cracked' the gp32 copy protection (I think the key was one of the developer's names or smth) but I doubt you'll get much help there.

The gp32 community is _very_ touchy when it comes to cracking and piracy. Gamepark has generously given us a free sdk, and I don't think anyone is about to help you with secumax, even though your goals seem noble.

Aha. I know very little about Sec*max. I certainly couldn't encrypt or decrypt any files, put it that way.

cowo: Are you saying that the MP3's are encrypted with it? Your question just seems a little confusing "I need sec*max to get the songs played by the device". Perhaps if you could explain in a little more detail?

Without knowing anything about the Yep Player, just by assumption, I'd say it needs some proprietary software that encrypts mp3s with secumax for the player, because they want the owners to use their (probably windows only *yuck*) software.

cowo: Thing is, from what i've heard, you need to sign a NDA with samsung to get to know about secumax specs, and they probably won't give a shit about an open-source project, unfortunately. There'd be no way to keep that project open source after adding secumax - even if samsung would give their specs out for you.

Try to talk to DarkFader or Firefly about.

Firefly has info about a sofware he created used to encrypt files for Gp32, but not published for security reasons ...

Go this Url and look for SecuMax

Yex is a C++ library and a simple text frontend that can manage files on a
Samsung Yepp-NEU Usb Mp3 player (USB IDS: Vendor 0x4E8, Product 0x5A00).

The big issue with this device is that the original Samsung software encrypts MP3 with SecuMAX before sending them to the player. The device itself plays only encrypted MP3s. In short: you won't be able to play the MP3s you download to the player with yex. As I don't have access to SecuMAX encryption schema this problem will likely remain, sorry. However you can use the gadget as a portable storage...

Read his site :rolleyes:
