RomVault v2.1.18 is released. RomVault is a new rom management tool. RomVault should be seen as an alternative to clrmame pro with some nice and new features that could make it perfect for managing large numbers of dats / collections using less time (one scan vs N dats a time instead of one scan for each dat) and giving you a nice easy to use GUI.

RomVault v2.1.18 Changelog：

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.
