*THIS IS A BETA RELEASE, NOT EVEN THE NFO IS FINISHED YET*
Xell dual boot has been added. Power on the xbox using the eject button to boot into xell. Yay libxenon
Bad blocks are now automatically taken care of and there is no need to run the output image through nandpro.
Font files have been added to the nand image to fix the issues with FSD. New filesystem package must be used. (thanks cOz!)
Jtag support will come soon, I should be getting a jtag xbox any day now to test on.
Retail profiles must be resigned to work for dev.
Things to come in final release---
* Big block support.
* INI files will replace the bat files.
* GUI Builder.
* hvxbootOS
* much more...
What's new/fixed:
* Added KV editing to the GUI
* Xell dual boot (xell-gggggg.bin)
* Bad block support
* Added font files to nand image to fix fsd (thanks cOz)
* No need to run image through nandpro anymore
* More error handling, builder doesn't say successful build every time
