Getting site developed in unity 2 to work in later versions

Hi. A friend of mine developed this site in 2011 in unity 2 but the content no longer works in the updated web players:

I was wondering if anyone knew how it update the original file to get it to play with the later unity player versions? Would I be able to adjust the source code for instance?

Your help would be much appreciated.

Many thanks,
Sam.

If you have access to the source code, one option is to upgrade gradually from version 2 to 3, then 3 to 4, then 4 to 5, testing every step of the way.

Keep in mind that this will most likely be quite a complex endeavour. (It might be simpler to rebuild the game with your existing art resources and the same game mechanics, especially if the game is relatively simple)

You can download the earlier versions of Unity here (you might need to be a pro user, as the completely free, fully-featured Community Edition only started with version 5).

Thanks for your response Catherine. I’ll see if I can adjust the source code!
