*THIS IS A BETA RELEASE, NOT EVEN THE NFO IS FINISHED YET*
Rgloader-dev 0v98 got leaked a few weeks back and contains a few bugs like slims showing up as test kits etc. This build contains the latest patches for all the xbox files but does not support big block or bad block.
If you manage the bad blocks yourself you might be able to get around the bad block issue.
Things to come in final release:
* Big block support.
* INI files will replace the bat files.
* GUI Builder.
* Xell dual boot & hvxbootOS
What's new/fixed in 0v100:
* Added 14699 patches
* Moved files location on hdd
* Slims show up as dev kit on 14699 without xbdm.ini or modded xbdm.xex
* Retail disc support on slims
* Added neededfiles.txt to the folders
