EightCounts has made a program for viewing old WarCraft replays. The program is still in a beta stage, although many people will probably rejoice since they now can watch all the old replays they have saved up.
Ever wanted to view your old replays but were unable to do so because it was from an old patch? To watch them, you were forced to uninstall the game and fix the right patch to do it. Now, with a new program you do not have to do so no more. Similar to the StarCraft tool 7x Patcher, there is now eVer-Craft, a program that allows you to easily switch between all the WarCraft 3 patches. The program was made by EightCounts, and is compatible with PC machines, but not MACs.
Still in the beta stage, still downloadable
The program is still in a beta stage, according to
KidArctica on SK-Gaming.com, and EightCounts will continue working on it. Although, you can still download it and try it. Download it » here. It is in ZIP-format, and there may be a couple of bugs.
