Xtf File.....
« on: July 04, 2003, 03:42:00 PM »
i think the default.xbe is something to do with it loading linux as it says linux in it wen i opened it with c++.
has anyone tried  putting the evox dash (for example) as default.xbe and deleting the one with the xploit.rar? try loading that.  i think the xtf files load the default xbe which in turn loads linux. so if we take out the xbe and just load exox it may work
or...
even better is there a mega x key xbe?
if yes rename to defaul.xbe and put the complex !loader files where linux should be eg,
c:fontsxtf files ------------->c:default.xbe--------------->e:linux[loads complex]----------------->boot !loader
just another theory lol

old and disproved theory, read around http://forums.xbox-s...ST&f=45&t=72446, already tried with evox, didnt work, if anyone else can verify... I'm betting theres something in the xtf files, but thats just a guess.

Well actually I know default.xbe loads linux it is just the linux loader xbe....  It has been around for a while.  The problem is trying to load other xbes in its place...  Which is loaded from the xtf file and i believe a check is made with the 2 RSA nums.....

it whould seem right before the xbe is loaded.....  then we could unpatch it right after the xbe is loaded.....

the exact spot is hard to tell... that is why i need to see if there is a util to open/edit/create these files

Thanks!

Also I noticed something else in the dump I have...  Just a little before the xbe is loaded there is a 'PE'  This could indicate the begining of an executables code.

Now as far as i understand it the font files are copied to memory then they are 'run'  so if during the running of the font files it sees PE it will believe it is an executable and then execute it...  Thus loading the 'program' that loaded the default xbe....

So if that is true we can replace 'code' after the PE (keeping the PE file format) and it will run our own code!!!!!

A lot of the info in this thread can be referenced from known info from earlier posts yesterday/today.

GRiFF, the XBox .xtf is a proprietary format/extension. The extension described in your link appears to be for software dealing with Sonars smile.gif [edit: at a glance, xtf's appear to be in the same format as font texture packed resources in the .xpr files (as is used for fonts in other xbox apps)]

p0pp, as for necessary tools -- XDK, VS, and a decent hex editor.  the .xtf's can be hand-edited even.

Executable code begins at 0x76FDCA

Just to say, good brainstorming between the two of you.

So, if the .xtf files tell the xbox to run a default.xbe file, and so far it only runs linux, could there have to be a certain starting line perhaps in the default.xbe?
