User Friendly Updater: [Valhalla Patcher (http://epiphany.networkchaos.net/Files/Valhalla_Client_Patcherv100.rar)]
kRO and Sakray can be updated with this program, simply move it to the directory holding the file(s) you want to update.
This was suggested by someone in another topic, I am just posting this to bring it forward so people don't post asking how to update kRO.
This seems to work fine, I don't use kRO, but from the looks of it, it should work.
