A friend recently led me to this site. It’s called The Cover Project and it has scans of video game box art. Apparently, there were folks who use these scans to recreate boxes for their games or create fake boxes for display, but I just like looking at them.
When I did, I discovered something interesting. The PAL box art is often different from the NTSC (re: US) version. I guess I already knew that. I had seen it before. But on this occasion, I was really struck by some of the differences. Super Mario Bros. is one. While I love the pop art, almost minimalist style of the NTSC boxes which just feature a frame from the game (in Super Mario Bros.‘s case, a rather dismal frame from the game, which shows Mario in what is obviously a no-win scenario and which speaks to me of the arduous nature of his quest), the PAL version has a beautiful piece of art that features Mario and all the game villains.
I also noticed a difference in Metroid. Again, the NTSC version had a still from the game, but the PAL version had a beautiful portrait of Samus.
These scans are all high rez and free. There are also scans not just of NES games but games from just about every system including the 2600, SNES, and TB16.
