This new MI fonts is excellent... but I am interested if there has been any progress on the original goal of exploiting a 2nd dash (hence no clock loop EVER).

Progress? yes.  Success? no.

The progress has been in understanding.

The authors of the font exploits have seen this thread and even posted a few words of advice amongst the 31-odd pages. biggrin.gif

It boils down to the fact that the font exploit does not rely on an overflow exploit alone, but also relies on the unique environment encountered during the boot-up initialisation of the XBOX (i.e. specific timings).  This environment is not present when a 2nd dashboard is invoked from the first.  Consequently, the identical exploit does not function.

Are you trying to modify the fonts for a different "enviroment"?

or are you working on something else.

It's much easier to produce a derived work, than originate.

It takes one level of skill (and mindset) to adjust an existing exploit, and a whole other level of skill to develop a new, original, exploit (which is what this would need to be).  And, I'm just not in that league.  sad.gif

why are the catfish fonts not the answer to this problem?

they load the ms dashboard, then you load PBL from the live tab, which becomes the "pheonix" tab (i like the alternate spelling hehe)

and this no clock issue.

unless i'm wrong...


So this already is working?

an idea u can run font signed apps from the mech fonts k so has some 1 signed the the ms dash with the font file if so does that mean u can run backed up games with out having to sign each one?

The dashboard isnt the factor that checks for any signing. Signing the xboxdash.xbe would only result in an error screen.

I think the purpose of this thread was to find a way to let the xbox boot to it's original dash with its original fonts and then after selecting the live tabs it loads the hacked fonts so you will have a complete safe hack.

Absolutely correct.  The term “double dashing” was coined for it.

PS.  All the techniques mentioned in this thead; stack overflows; heap overflows; function detouring; etc. are covered in detail in the recent book “The Shellcoder's Handbook : Discovering and Exploiting Security Holes” (ISBN: 0764544683) for anyone interested.  (My current bedtime reading smile.gif )

ok how about when u go into the live section it does a mini reboot (not a full one where u see it go in to the X) would it be possable to load diff fonts after the reboot i mean mayb tell it to look in the live section on reboot in the reboot.xbe that u put in. Im almost sure u cant load new fonts when the xbox is running but i thought id ask just incase its a poss.


I think in order to do that the xboxdash.xbe needs to be altered so that the reboot process would be different. Too bad we can't change it though

Yeah you can do it, go post that here instead, MS Dash Hacking Forum. I'll help you out there if someone doesn't beat me to it.
