IIRC, when you click the link to download a ROM, a popup will come up with some anime p*rn pic thingie and a button that says "click here to proceed." Click the button and it will display one of those top site lists. You can close the popup window and then click the download ROM link again, and a save prompt should come up. Sometimes you will have to wait a few minutes between downloads as well.
Actually when you click the download now button the second time you get a window with one of those fuzzy numbers screen. Just enter the number in the box then click enter and the download will start.
Games and emulators won't open (at least the game won't) for some reason when all of the stuff is put in a single folder. For whatever reason, I have to always have it and all of the .ini files and such on the desktop for it to work. It works great though. My friend had the same problem with most of you; I don't know if he figured it out or not, but I'll ask.
