Command & Conquer Generals: Zero Hour How to Make a New Faction?

Hello,

I had some free time so I tried to make a new faction for Command & Conquer Generals: Zero Hour by following a guide. After I finished with everything the faction did not appear in the game so I removed all the code and tried to do it again but with another guide. Unlike the last time, it did add the faction but when I tried to play with it, the game crashed.

I was thinking if anyone can help me make a faction or make a proper guide so other Command & Conquer Zero Hour players can make factions too.
