Not really. Depends on the game though. A lot would be 480p and still not look right on a 720 or 1080 tv even though it would switch modes to 480. Again though it depends on the game. Some you hold a couple of buttons while loading to access the higher res or something, others in menu options and those with widescreen support will fit a little better etc, but overall I didn't think it was all that great.
