mccodes v2 security

[JamesC]

I've started to create a game again with the old mccodes V2 engine, I had a look at gangster legends but the nostalgia of mccodes is making me go for that.  Although even with my little knowlege of web security its pretty obvious how insecure the code is.

Was wandering if it is just some quick fixes that i could learn how to do in not much time.

Or if anyone has a secured version of the basic mccodes v2 that I could buy for a little bit. (I have bought the licence for it already)

I'm quite a creative guy so can throw things around to make it look good and create something surprizingly appealing to users, but my actual lack of knowledge of coding does lead to security issues and really unclean ways of doing things. But am having fun with it

first thing I would do is go through globals and sglobals and sort the user queries out as they were fairly lazy and just used u.* from users
