any chance unsigned code will be playable on stock modded/hacked 360?

    There is still some stuff being done on the OpenXDK:

    This is the largest step forward I've seen in awhile.

    ASSEMbler is right if you remove the efuse you can't play any of the new games. Also downgrading is not possible any more

    Sorry, dunno if Assembler is wrong or right, but definilly ur wrong, cause u cant remove the efuse, just a resistor that gives power to blown the efuse.

    To clarify this:

    If you remove the resistor, the efuse cannot be burnt anymore, so the pre-4552 (=possibly exploitable) kernel versions can not be revoked.

    If you remove the resistor, and then upgrade, you could *theoretically* downgrade again by modifying the flashrom. Or have a dual-boot solution (basically with two flashroms). That way, you could boot a new and old kernel, one for gaming, other one for exploits.

    However that still doesn't solve the other problems (mainly that if you have already updated before removing the resistor, there is no way back).

    You can already run homebrew on the Xbox 360 !!!

    do you know the XNA? there's a version avalaible to amaturers coders, and you can program things with it. Don't know how it work tough.

    The 3 biggest limitations with XNA are:
    1.You can only program in C# (i.e. managed code which means you dont get the raw power of the machine)
    2.The cost to be able to run your code on the 360 is expensive.
    and 3.You cannot talk to the outside world at all (i.e. you cannot do any networking of any kind to LAN or internet)

    I suspect limitation #3 is there because they dont want any software for the 360 accessing anything other than Microsoft XBOX live servers (or specially approved servers run by EA and others for their XBOX live games) wilst at the same time, they dont want just anyone being able to write games that can talk to each other over XBOX live.

    That if you get the CPU key you can use the hypervisor hack and run unsigned code (linux too but who cares...).

    except that you need the hypervisor hack to get the cpu key.

    or is it the other way around? you need the cpu key to be able to backpeddle on the firmware so you can get the hypervision hack? and for all of this you also need a chip right?
    baby steps, but things are heading in the right direction no?

    For what I could undestand, you need the CPU key to open the vault, but the problem is that the key is in the vault too.

    Talk about paradoxes...

    No, the CPU key is not in the keyvault. It's in the CPU. The keyvault is in flash.

    Just a crazy idea... Can you convert a retail into a debugger by replacing the NAND flash?

    I mean, if you get the NAND flash from a 360 debugger dumped and decrypted and then encrypt it with a CPU key from a retail unit, and then flash the retail unit with it...

    I have a feeling it would be done already if it was possible, but I just have to ask anyway :)
