Recently I have been working on the conversion of the hiscore script to work on a 2.2 version until i get things sorted out. From the looks of it and time spent, i must say that it is was harder at first but now it seems quite easy to work with, especially if you have good tools to help you find your way around the source code.
At the moment I am working on the application feature that I added in 2.1.x series. If I am unable to get it up and running I will drop it until hiscore 3.x comes out. But i have got up most of the basic hiscore up and running but you can’t manage it at all as the admincp is having issues.
One of the biggest issues is the php5 and mysqli in the source code it is pretty annoying to have to convert everything to a suitable format, but we have to do it to make it work.
i’ll post on later for any updates.
