well,you could try reversing,or you could update the emu to a newer version of sro..(this is the one I'd do)

but if I were you,I'd start a whole new one,in a newer language (java,c#,c++,etc),and I'd use some of the packets & some well-done parts of sea-emu..but I'd never work on one which uses ini files to store infos & written in vb6..that's my opinion
anyway,this:

guide can be helpful in the reversing part^^
