Just saw this on AeroXP:

Anolis.Resourcer
A ResHacker clone developed as a testbed for Anolis.Core and to replace ResHacker (because ResHacker doesn't support x64, XN Resource Editor (ResHacker's spiritual sequel) doesn't support multiple-language resources and crashes a lot, and other utilities rest cost actual money. It has a powerful yet simplified UI that doesn't duplicate commands or confuse the users with special-case handlers (which ResHacker and XN have in spades).
It's open source, free, supports x64, miles better than the rest, on par with Restorator 2007 (which is expensive)
