Just a heads up. The kernal 5849.1 has arrived for xbox xbes (in the PAL territory anyway). In this kernal you will find no search string that popular patching program uses for old bioses. (Which I said all along.)
1. The no patch hacks bioses should work. (which proves they never used this method in the first place despite what some ppl may think on here.)
2. Another method definitely works.
3. Different patching programs use different methods.
4. It is unknown whether you have to patch it anyway. (I cant personal test because im on a no patch hack bios and cant go back to old versions due to having a 1.4 xbox)
So good luck and have fun (if its actually required for you)!
Also if you remmber last time things changed. It chnaged again very quickly and a shorter string was produced. So this couldn't be the end. (Depends on whether that was the last xdk or not tbh... I dunno)
