My question is: How to implement the sv_cheats cvar (or whatever it's called ; 0=No Cheats, 1=Cheats Enabled) I know I need the source for this, but I don't know a couple of things:
1. What compiler should I use?
2. Which part of the source is the proper place to put it? (what .h or .c file)
3. What would the Cvar need to look like to be recognized by the engine?
I DO NOT know ANY programming languages, but am willing to learn for a purpose such as this. I know I may sound annoying attempting to make cheats enabled, but Quakeworld engines have this command, so why not regular Quake? If someone is willing to help me with this, it will be greatly appreciated!

P.S: I would also like to know how to compile for a PSP slim version if at all possible, and how to allocate more ram.
Thanks,

EDIT: I actually wanted to use GLQuake's engine, not ProQuake's.
