i have a little xbe i made that just renames some files and then does a power cycle to the box. when i tried to sign it with xbedump -habibi, everything 'passes' except the 'header size' check. it fails. is there some sort of adjustment i need to make to my project properties to get this thing sign-able? thanks!

if it's a debug *.xbe,try to compile it as release or vice versa.then check again if it works...

thanks! i'll try that. it's compiled for release, so i'll try debug...

However, can you or someone else explain or point me to an explaination of what xbedump is doing when it checks 'header size'?

I've gotten this a number of times with different XBEs, and in all but I think one case they worked anyways.

edit: I was using habibi key at the time as your are, maybe it's a related bug?

ok cool thanks! it wasn't working with a habibi font exploit. i'll try it with a game save to see if had something to do with the font...

I've seen this. Only got it when I updated to a later XDK. I think M$ has slightly altered the XBE file format in the linker of the newer XDKs, and xbedump just doesn't know about it.

I recall I found a workaround, and that that was to delete the XBE produced, and run CXBE on the *.EXE that is also produced. CXBE turns the EXE into an XBE in the old format, and xbedump then signed it with no problem.

According to a file on the Xbox Linux project's site (Xbox Linux XBE Bootloader), the same site that is responsible for making XBEDump, you can have a valid header for the Xbox kernel which doesn't pass XBEDump's tests. XBEDump just makes some assumptions on what XBE's should look like, and if they don't look that way then XBEDump complains, but XBEs don't have to look that way. A later XDK (which requires VS .NET a.k.a. VS7) always made XBE's that XBEDump didn't like. The same code on an earlier XDK (which didn't recognize VS .NET, and so needed VS6 to install) made XBE files that XBEDump liked quite well. Do not use the CXBE conversion as mentioned above. I thought it was a great idea too, but even though those XBE's pass XBEDump's tests, there are other problems. (XBEPack doesn't like the XBE's that CXBE makes.) Rather that create that problem, I suggest to just ignore XBEDump's results since they are known to be imperfect.

thank you very much guys! this is all very good to know. even if cxbx isn't the way to go, i was wondering how one makes an xbe using the only the openxdk
