Don't we all want to go back to see how the top players of yesteryear played? To watch the awesome matches of TillerMaN, HazeeM, and many more pros, well then don't go patching yourself back all the time, it's time to adapt.

That's just what one of the members on WCReplays has done, EightCounts, has made a software which allows you to switch between all versions (ROC too) of Warcraft without any hassle, 

"I saw tons of threads asking for ways to watch older replays plus I too wanted a way to watch older replays and it really spiked when people talked about Partisan ranger getting spanked by a solo TC and at the time I didnt know how to view it. I was told to reinstall and patch up to it but that was too much of a chore. What also contributed was wczei but he discontinued it. So i decided to try my hand at writing a similar program and there you have ever-craft.

I am glad how people are receiving it and that it is still a work in progress. Some bugs but I am working them out. And that I will try to implement any suggestions that people give me into further updates. I will also look to spice up the GUI soon enough but for now this works."

Note that this is a beta release, and that it works for the Windows Operating System only, also EightCounts is working on perfecting the program, so any suggestions or feedback you may have you can put forth in the Original Post link given below.
While the file is 36.5mb in size, it should be worth it for all those people who love to watch replays and had problems before.
