You can use the memory editor to edit the weapon, armor stats.
I know a Chinese site that has tutorial show you how to edit the memory for weapon, armor, mob. However you have to be able to read Chinese.
Sadly that i don't have time to translate and i highly doubt there are any English speakers there. I am not posting the site for now since i am not sure if it against the rule of this board.
You can see what i have edited for my character.

I probably modded too much, but i am bored and i just want to plow through everything.
