But it also supports save states and other emulator-style functions, and outputs in HDMI. And it uses the real controllers for those (except for Game Boy, naturally). The RetroN 5 plays real, vintage game cartridges, and lots of them – NES, Famicom, Genesis, Mega Drive, SNES, Super Famicom, Game Boy, Game Boy Color, and Game Boy Advance. These are the people who, hypothetically speaking, stuff a Twin Famicom in their suitcase while on a business trip to Tokyo. On the other side, there are people who strive for absolute authenticity: real cartridges on real consoles, played on CRT televisions with real controllers. These are the people who like emulation the most, either through downloading ROMs or official downloadable re-releases of games. On one side, there are people who want all the modern conveniences, both in-game and out: save states, fast-forward and rewind in the games, and wireless controllers, high definition output, and non-finicky hardware to play them with. Let's call it two for the sake of argument. There are at least two schools of thought when it comes to playing retro games.
