I have over 800 games from an old site, how do I make them so the scores and such will work on the activity mod?

I do not think they all have a same way they can so the scores and such will work on the activity mod.
I think that each game has its own way to do it.
Perhaps there are some common grounds for change genres.

I have about 440 games that work perfect with the activity mod (around 100Mb space in my server). I would be happy to exchange then with 200 (or less) of your own if working with actiivty mod.

I can give the full list here (Dwho now my full list)
