December 20th, 2013, ROMVault 2.1.18
Already fixed one bug caused by not having a ROMRoot directory setup when you try and run RV, and trying to track down another bug.
If you have been getting the error message ´comparing null ulong?´ please download and run this version.
I do not understand what logic is leading to the reason this message is being displayed. So this version will send me a more detailed message about it.
If you are at the point where you can reproduce this error repeatedly, please get a hold of me, I would really like to get to the bottom of this one ASAP.
