Windows/Mac/Linux: The Nintendo 3DS is a great little system, but with a maximum resolution of 400 x 240, it's not exactly a looker. Citra is an emulator that's still very early in development, but features a way to upscale 3DS games to 1600 x 900. Citra's very much an open-source beta product, but it's at a point where a small handful of games run at reasonable speeds. The most interesting part is the new feature that upscales games to HD resolution. As shown in their collection screenshots, in some cases, games look incredible. This makes playing 3DS games on a big computer monitor a much more viable thing. Of course, as with any emulation, the biggest trick is getting games, and dumping your own into Citra from your 3DS is a convoluted, but doable process. It's still a ways off from being a viable means to play 3DS games on the big screen, but it's worth playing around if you're curious.
