I had one of those but my screen was scratched up and I had to send it back. Still waiting for my replacement. When I played with it I got oldboy (B&W GB) to work. I only tried Super Mario Land but it worked perfect. I never thought of trying to look for newer systems (PS2, Wii, NGC, etc....) because the HDD was small with only 14.9gb usable. My order form email states that my replacement will be here March 23rd. Veristic did you get yours to work with the Wi-Fi rom downloader or did you add it to the unit yourself (USB)?
