I'd also suggest Winrar instead of Winzip (from www.rarsoft.com ) - Winzip is only for those that don't want to let go of the past from when it used to be the best, it's simply not anymore.

Do the emulators on this site suck? Since they won't be the latest versions, then yes, most likely You should be able to get the latest from either www.zophar.net , or direct from the creator's website which should be in the Help > About menu item in most emulators
