Hi Stuart,
Firstly, I couldn't review your playstations2-cheats site because something on your site kept crashing my Netscape consistently. Don't worry too much about it, because my Netscape's unstable, but just so you know in the future in case you get any complaints like mine.
On to Cheatmasters - great work. Just a couple of minor points to go through :
==============================
Browser version : Netscape 4.7
OS : WinNT
Screen resolution : 800X600
Speed : decent
==============================
1. The 'buttons' right up the top (HomePage, Submit Content, etc.) - are they supposed to be clickable? If not, then get rid of it.
2. In the 'Shockwave Arcade Now Open' section (in the middle) - "At the moment
their are 6 games..." Uh hem.
3. JScript problem with your date : I get 10/2/100
4. Design-wise :

very, very good use of tables and layout. Pleasing on the eye (though I do have some minor reservations about the faded yellow, but that's just personal taste). Great work.
5. Usability wise : quite good. Not hard to get around though it does take some getting used to. Just fix problem 1. and you'll get a very good from me
Overall, great work. You oughta be congratulated.
