Oops, that should have said Unknown[MAX_TILES]; .. fixed it .

I have never learnt any PHP beyond "hello world", but it sure looks like great stuff (it actually looks a lot like C/C++) . I didn't really have much time to look through the structures you defined, but I guess FastBlit would be a good way of putting it ;D.

I've never actually used most of the information in J2T either, I just did some last-minute research to provide closure for my article. So I'll be really glad if people will fill in the missing information, publish it in ERE, all in time for my "first return visit".
