RomVault v2.1.20 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 v2.1.20 Changelog：

HAPPY NEW YEAR. And after much searching and trouble I believe I have finally tracked down 'comparing null ulong?' error. You had to have: a) a missing CHD file that did not give a SIZE in the CHD DAT b) a missing ROM file that was zero length and so no CRC supplied in the DAT c) have a fix for the CHD d) have the order of things so that the CHD would be fixed before the ZERO length file. And then you got the ulong? error message. Anyway finally tracked that one down, and put the correct checks in place to handle missing Size/CRC information better. So go grab 2.1.20, and keep on fixing.
