Just as everybody has said prior, it looks AMAZING on the big screen. I played around with the filters, but in the end I just left them off. Some games look better with them on, but they all look great with them off.
The controller isn't THAT bad. Maybe it's because I'm used to using a variety of controllers with emulators on my computer, but this controller doesn't seem as bad as people are making it sound. Is it a great controller? No. Will I use it? Not really. That's why they give the option to use the old controllers. I do wish they had somehow made it to where I could use the systems' official wireless controllers though.
Death Grips: No major gripes here. The Genesis/MD was a little tight, but nothing major. However, I ran into one big issue and so far it's my only complaint:
Yoshi's Island. Holy crap is it hard to get that game to fit into it's slot. A lot of times only half of the cart goes in, but the game still loads. If I manage to push it down all the way, then it's freaking hell trying to pull the game back out.
That's it! Was totally worth the money and wait. Now if you'll excuse me... I have some games to play.
