I'm a bit late to this thread, but I am into retro gaming. I own a Nintendo DS, and the main games I pay on it are the Game Boy Advance versions of Super Mario Bros. and Super Mario Bros. 3, as well as the DS game Tetris Party. In addition, I own an original NES system which works perfectly to this day, and even have the NES Advantage controller for it, as well as two NES Zapper guns, one red, and one gray... again, all work perfectly. Finally, I also own an original Nintendo Game Boy, which works pretty much perfectly, but just recently the screen is starting to show signs of age, and some pixels go missing in the game image.
