how about you replace the downloader.xbe in halo with an app, wouldnt that be easier.

That file can't be resigned , only the map files from halo (2).
It would be more easy to edit through, but we can't resign it so the 360 won't launch it.

Sorry for double post, can't edit my post >_<



zerosignal0 , how and where did u put the dash?


And did u hex a few things?
Because it looks like you could change the loading path * first 12 lines in hex *

[zerosignal0]

see thats not going to work... heres why. Even If you do change the hex to look for the a file in a different location its still putting .map as an extension at the end. That is done by the games xbe so good luck changing it. Im sorry but again I really dont think this is going to work out for ya.

Here are my $.02

Can we play Xbox 1 backups on the Xbox 360?  Yes, I wrote one of the first tutorials to do so, you can find it in the backup FAQ.  Can we inject modified data files into the image before burning, and will it work?  Theoretically, yes.  The only thing signed on Xbox 1 discs are XBE files.  Almost all data files are unsigned.  we can modify...say...a Halo 2 map, fix the encryption...then inject it into the image and it will most likely work.  I haven't tried this yet, but everything logically says "you can play modded Halo 2 maps on the Xbox 360 using the firmware hack".  Go on Live and have fun with being permanently banned though.  Anyways... where does this get us?  Nowhere for right now.  The only files that we can load any homebrew from are XBE files.  It just so happens that we cannot modify these files in any way, because they are signed.  It is possible that somebody may find an exploit in a certain Xbox 1 game's unsigned data files.  This, coupled with the firmware hacks, would get homebrew running at least through the backwards compatibility emulator.  The only problem we face is finding this Xbox 1 game data file exploit.  And before you ask, no none of the Xbox 1 exploits using 007, Mechassault, or Splinter Cell will work.  These relied on buffer overflows.  The Xbox 360 is nearly impervious to buffer overflows.  For now, we wait until somebody can find an exploitable data file in an Xbox 1 game (on the backwards compatiblity list).

uhm not to sound like an asshole but why is it that Im the only one here that actually tried anything? I keep hearing "theoretically" it should work and maybe if someone did that but no ones done anything but me.

[Dark_Neo]

As someone who knows quite a bit about the Halo 2 map format I can safely say this will not work. Why? Because the "signing" on the Halo 2 maps is incredibly simple, it's more an integrity check than a signature. Which means they're not trying to protect anything security wise, the only way I could think of executing anything from a Halo map is a buffer overflow which as Textbook said is nearly impossible on an Xbox 360.

The only thing about Halo 2 maps I'm not familar with is the files to install new maps from XBL, if this is what you're on about then maybe it will work, I've no idea about that. Either way I'm not saying people shouldn't try it, just making sure you know how likely it is that it will suceed and the reasons for that.

you mean the downloader.xbe ?

[Dark_Neo]

No, that'd be a no-go because of signing, I'm on about the actual files it downloads. Did a little research, these are just map files, last time I was paying attention to this was before the map pack was released, and there were several theories about how new maps could be downloaded, so disregard that comment

Sorry to bust your bubble, but you did come off as an asshole, nearly attacking me because I haven't modded my Halo 2 and wasted a blank DL for no reason.  Why should I try modding a map that can't launch an xbe ??  I don't even mod Halo 2.  I realize that might come as a surprise to some people who see my avatar and read my post about map signatures, but it's true.  I'm more about modding the actual Xbox or Xbox 360.  The reason why nobody has tried anything is because we know it won't work.  I don't know about you but I'm not about to waste 2 or 3 expensive DL discs on some pointless modded maps.  If you can provide some insight into a possible way of launching an XBE or some other game data file exploit, please do tell and I will be the first one to test it out.  I want homebrew on the 360 as much as anybody here, so I would love to be a tester if there is even a slight chance of loading an unsigned XBE through a game data file.  I'm sorry, but it appears to me that your most recent post sounds like you are the only one contributing.  Excuse me, but what have you tried?  Because whatever you have tried already hasn't yielded anything, so you are no further than myself or any of the other 250,000+ members of this forum.  I don't see any contributions you have made to the scene.  I don't see the hours put into testing or writing a tutorial so others can get Xbox 1 backups on the Xbox 360.  Like I said, theoretically, yes, you can put modded maps on a Halo 2 burned disc and play them on a 360.  Is there a reason why I would need to escalate my "theory" to proof?  Where does that get us?  Nowhere.  It gets me a useless disc full of stupid modded Halo 2 maps.  By all means, continue with this thread, as this is a very important area and may be the first area to attack for getting homebrew on the 360.  Just come up with some better ideas.  Listen to myself and Dark_Neo, there is no way of running an unsigned xbe through a modified .map file.

I applaud anyone trying anything to get Homebrew running. But surely the answers should be it SHOULDN'T work rather than it won't so don't try.
I'm old enough to remeber the Spectrum days and an independant programmer made a game called Bobby Bearing, ijn this isometric game he had a round ball going through a round hole, I know that doesn't sound a big deal, but the thing is every other programmer said "But you can't do that on the spectrum it's impossible. It needs to treat all graphics as 2D squares". The programmers reply was "Nobody told me that".
My point is unless you have tried this yourself and proved it wrong then dismissing all ideas will mean homebrew on the 360 will go nowhere.
Don't get me wrong it shouldn't work but then isn't that what The Specialist said about the first release of 360 dvd firmware and was proved wrong?

People have tried on the Xbox 1.  At this time, there is no game data file for any game that can contain and launch an embedded, unsigned xbe.  Now give me something intelligent to try and I will try it.

[Tomobobo]

I mean, please don't rip into me because I have very very little knowledge of programing, but, does the .xbe that we're trying to launch necessarily need to be embedded within the .map file?  Couldn't you in someway, write a .map that just says "hey launch this over here" just by making the box try to load that particular map?  That was what my understanding of how this was going to work, of course, I probably misunderstood and overestemated the possibilities and limits of creating some sort of hacked map file.

Nope, will not work.  Which is the reason for my little yelling spat.

it could work with the 360 dont knock it tell you try it
