Couple of things:
The emulators page is broken. When I click on one, it always gives me 404 errors. Well, I assume it's not broken, but rather you don't have the files; I'd suggest, for emulators, to simply link to the official website's download page, and on your page, put a review, rating, a quick description, etc.
You don't really need to provide a mirror for an emulator, since it's already hosted somewhere safely.
Also, your BSnes version is outdated; current one is 0.030.
To keep up with other PSX, GBA and such emulators, I'd suggest giving a look at NGEmu.com and see what they list; they've got a huge list of "new-gen" (not next-gen) emulators. Just borrow theirs
Also, the Java Chat appears to be broken; I got a NumberFormatException. And the title of the Java Chat page is still "GamingDimension.net". As such, all the links are broken (well, the php includes are broken).
Last, when I type something in the search box, the text is a little too dark; it's viewable, but it could use some lighting up.
