Grand chase season 1 private server is it possible to add season 2 content to 1?

Like new characters?

I guess, but i think you need the source code for this

I think it's possible but not very easy to do it. Some databases and server files need to be eddited and is not difficult to broke things. I think that is easier to replace somethings. Cause it's like, u can try add some new char but u can also replace the Ryan transformation to another char and test it. If u learn and get that, u can bring to us the result and help the community somehow

Where did you get Season 1? Aren't all the links gone? I'd love to have it, since I started back in 2006.
By the way, I think it wouldn't be possible due to the way the game works. Not sure how to explain it but there was a limited number of characters and classes back in the day, so I don't know if you'd be able to modify that.
