Sim City 4, How can I mod it? Options

[Scorch]

If anyone can give me a tutorial, I will greatly appreciate it.
Actually, if anyone could give me clean files, that would be great too!

(Before anyone starts flaming, YES, I already searched Google and found nothing.)

I cannot find simcity_1.dat in my Maxis files anywhere.
I downloaded ilive reader, yet it's like trying to find a needle in a haystack. You can't find what you're looking for.
When you do manage to find something, it's impossible to mod it simply because there is nothing equivalent to something like an .ini file.

i have the sims city 4 deluxe edition and i found simcity_1.dat in Maxis\SimCity 4 Deluxe along with simcity_2,3,4,&5.dat

and thanks for the link ill have a look but if there are no ini files you may have to go in with a hex editor or worse
