  Version 3 Build 3

    Bug Fixes
    Dynamic size when reading full dumps of "Corona 4GB", should work with XBOX One

   Version 3 Build 2

    Bug Fixes

   Version 3 Build 1

    Support for new dashlaunch/xeBuild
    Latest XeLL
    Support for 16537 dash
    XVal, why? no reason
    XVal related function but for secdata.bin
    Get Latest System Update function (hope MS won't bother JR downloading it)
    xsvf LPT support for XP users (for those cheap asses who didn't buy a JR-P)
    ECC files updated with new XeLL
    both minor and major bugfixes and bug creations (As always please report bugs to make JR better )

Build 290

    Changed way it handles ECC on 14719< nands Instead of Write ECC* there is now Create ECC* (blame Martin_C) It has been altered due to a large number of users who didn't understand the process, and to bring it in line with the normal process. For all RGH, Read Nand, Create ECC*, Write ECC, get CPU key, Create Image and Write Image. Create ECC* will now transfer your KV into the premade ECC, so people wont lose it (who does that anyway) and so we won't have people asking why they can't see their DVD key in XELL
    Added Console type on CPU Key database. If you double click on a row the CPU Key will be loaded and if you press the ... button to load a nand, you should be automatically taken to the serial folder it belongs in (if you still have the nands in their respective serial folders) Scan Folders should auto populate info on previous entries
