Or you could you know, fix the system and make it dynamic… it’s not hard to do so
What might not be hard for you, could be a major challenge for another person. Not everybody has the same skill level as you. This guy clearly is far below where you stand. So for everybody saying “omg it’s so easy to do, I don’t understand why you haven’t done it, blah blah blah”, I’m crossing my fingers and hoping that at some point you’ll understand the concept of different skill levels. Once more, just to be redundant: what’s easy for you, might not be easy for someone else.
With that being out of the way….
Sekiguchi, you’ll have to open the source code in VB6 (I believe for both the client and the server), search for maxclasses, and change the value there. Then you’ll have to search for the current classes in the code and either remove them completely, or edit them yourself to fit your needs. After that, compile everything, and you should be good to go.
