Hello,
Nice site.
The background color is conflicting with your text color. It is a little hard on the eyes to read.
For your news on the right, I suggest condensing it to say 4-5 items for PC, XBOX, etc. and then have an archive link at the bottom.
I found that once I clicked on your links on the right there is no way of getting back to your home page.
On your home page i wouldn't make your ad banners so dominate.
For better
SEO I would keep just this in your title:
<TITLE> Cheat Cheats Trainers Savegames Codes Tips Tricks Walkthroughs for PC Xbox Playstation 2 C64</TITLE>
And get rid of the javascript that changes it.
These extra fancy javascripts may slow down your webpage, you can check on that here:

I would have one button for 'contact' and another for 'Submit Your Cheat'-submitting cheats/walkthroughs, etc.
It will make it easier for people who breeze through a site looking for a specific thing.
Great site for walkthroughs!
